ALSA: interwave: guard PM-only restore helpers with CONFIG_PM

The InterWave PM patch added snd_interwave_restore_regs() and
snd_interwave_restore_memory() as static helpers, but both are used only
from the resume path under CONFIG_PM.

On configurations without CONFIG_PM, such as alpha allyesconfig, this
leaves both helpers unused and triggers -Wunused-function warnings with
W=1.

Move the PM-only helpers into the existing CONFIG_PM section. Keep
__snd_interwave_restore_regs() outside the guard because it is also used
during probe-time initialization.

ALSA: interwave: add ISA and PnP suspend and resume callbacks

interwave still leaves both its ISA and PnP PM callbacks disabled even
though the shared GUS suspend and resume path now exists.

This board needs InterWave-specific glue around the shared GUS PM path.
The attached WSS codec has its own register image that must be saved and
restored across suspend, the InterWave-specific GF1 compatibility,
decode, MPU401, and emulation settings must be rewritten after the
shared GF1 resume path reinitializes the chip, and the probe-detected
InterWave memory layout must be restored without rerunning the
destructive DRAM/ROM detection path.

Track the optional STB TEA6330T bus at probe time, restore its cached
mixer state after resume, add resume-safe helpers for the InterWave
register and memory-configuration state, and wire both the ISA and PnP
front-ends up to the shared GUS PM helpers.

The resume path intentionally restores only the cached hardware setup.
It does not attempt to preserve sample RAM contents across suspend.

ALSA: gusmax: add ISA suspend and resume callbacks

gusmax still leaves its ISA PM callbacks disabled even though the shared
GF1 suspend and resume path now exists.

This board needs one extra piece of PM glue around the shared GF1 helpers.
The attached WSS codec has its own register image that must be saved and
restored across suspend, and the MAX control register must be rewritten on
resume before the codec and GF1 sides are brought back.

Use the existing wss->suspend() and wss->resume() hooks for the codec, then
wire the driver up to the shared GUS suspend and resume helpers for the GF1
side.

ALSA: gusextreme: add ISA suspend and resume callbacks

gusextreme still leaves its ISA PM callbacks disabled because the shared
GF1 core had no suspend and resume path suitable for PM recovery.

Resume on this board needs one extra step before the shared GF1 path can
touch the chip again: the ES1688 side must restore the GF1 routing. Split
that routing sequence into a helper, reuse it for probe and resume, reset
the ES1688 side first on resume, and then wire the driver up to the shared
GUS PM helpers.

This restores usable post-resume GF1 operation on GUS Extreme without
rerunning probe-only detection in the shared GF1 path.

Wire the driver up to the new shared GUS suspend and resume helpers so a

probe-only detection or tearing down the runtime bookkeeping kept by the
card instance.

ALSA: gus: add shared GF1 suspend and resume helpers

gusclassic and gusextreme still leave their ISA PM callbacks disabled
because the shared GF1 core only provides probe-time startup and full
shutdown paths.

Those helpers are not suitable for suspend and resume. They reset software
handlers and tear down runtime state such as the DRAM allocator, timer
state, DMA queues, PCM state and UART setup. Resume instead needs a
narrower recovery path that rebuilds the GF1 hardware state without
rerunning probe-only detection or discarding the bookkeeping kept by the
card instance.

Add shared GF1 suspend and resume helpers for that recovery path. Suspend
now quiesces GF1 PCM, aborts queued GF1 DMA work, resets the UART and
powers the chip down without tearing down allocator, timer or rawmidi
bookkeeping. Resume rebuilds the GF1 hardware state, restores timer and
UART handlers, and brings the chip back to a usable post-resume state for
the ISA front-ends.

The scope is limited to restoring post-resume usability. It does not
attempt transparent continuation of active GF1 PCM or synth state across
suspend, and userspace may still need to reprepare streams or reload
onboard sample data after resume. Open rawmidi substreams are restored
only to a usable post-resume state.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using

git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.
