vt: export RGB offsets with FBIO_GETRGBOFFS

Add a new ioctl to vt to make it possible to export RGB offsets
set by vt drivers. This is needed to fix colors on X and Mesa
on some machines, especially on modern PowerPC64 BE ones.

With the appropriate changes in SCFB, to use this ioctl to find
out the correct RGB offsets, this fixes wrong colors on Talos II
and Blackbird, when used with their built-in video cards.

ofwfb: fix vga/hdmi console with ASMEDIA during boot on powerpc64(le)

On recent OpenBMC firmware, the onboard ASMEDIA video card framebuffer
address was removed from device tree for security purposes (value is set
to zero to avoid leaking the address).

This patch works around the problem by taking framebuffer base address
from the "ranges" property of a parent node.

ofwfb: fix incorrect colors on powerpc* and add new tunable parameters

- Implements little-endian support (powerpc64le)
- Adds 'hw.ofwfb.physaddr' kernel parameter so user can manually
provide correct address if it's not detected correctly
- Adds 'hw.ofwfb.argb32_pixel' so user can set it manually if
colors are inverted due to incorrect pixel format (default = 1)
- Automatically selects RGBA32 pixel format if NVidia graphic adapter
is detected (sets hw.ofwfb.argb32_pixel=0)

Machines equipped with NVidia graphic adapters tend to use RGBA32
pixel format. By default ARGB32 pixel format is used, proved to work
on machines equipped with ATI graphic adapter and the onboard adapter
used on Talos II and Blackbird machines from Raptor Computing Systems.

Enable use of ofwcons for early debug

This change enables the use of OpenFirmware Console (ofwcons), even when VGA is
available, allowing early kernel messages to be seen, that is important in case
of crashes before VGA console initialization.

This is specially useful in virtualized environments, where the user/developer
doesn't have full control of the virtualization engine (e.g. OpenStack).

The old behavior is preserved by default and, in order to use ofwcons, a few
tunables that have been introduced need to be set:
- hw.ofwfb.disable=1 - disable OFW FrameBuffer device
- machdep.ofw.mtx_spin=1 - change PPC OFW mutex to SPIN type, to match kernel
console's mutex type
- debug.quiesce_ofw=0 - don't call OFW quiesce, needed to keep ofwcons I/O
working

vt/ofwfb: Check that /chosen/stdout is valid before using it in initialization

The FDT implementation of OF_instance_to_package() backend checks the
cross-reference to get the node. On failure, this returns the input handle
unchanged. In the case of ofwfb attachment, if /chosen/stdout property does not
exist, sc->sc_handle is either garbage or 0, which then gets propagated to node.
This will prevent "screen" from being used, resulting in not properly attaching.
Correct this by matching the code in ofwfb_probe().

Avoid writing to the frame buffer in early boot on PowerPC if the CPU's
MMU is disabled.

This expands some earlier logic and avoids a number of potential problems:
1. The CPU may not be able to access the framebuffer in real mode (real
mode does not necessarily encompass all available memory, especially
under a hypervisor).
2. Real mode accesses generally assume cacheability, so it might not
even have worked.
3. The difference in cacheability between real mode and later (and
potentially earlier) points in the boot with the MMU on may cause
ERAT parity problems, resulting in a machine check.

This fixes real-mode (usefdt=1) early boot on the G5 iMac, which was
previously broken as a result of issue #3. Late boot will require some
other fixups.

Move the powerpc64 direct map base address from zero to high memory. This
accomplishes a few things:
- Makes NULL an invalid address in the kernel, which is useful for catching
bugs.
- Lays groundwork for radix-tree translation on POWER9, which requires the
direct map be at high memory.
- Similarly lays groundwork for a direct map on 64-bit Book-E.

The new base address is chosen as the base of the fourth radix quadrant
(the minimum kernel address in this translation mode) and because all
supported CPUs ignore at least the first two bits of addresses in real
mode, allowing direct-map addresses to be used in real-mode handlers.
This is required by Linux and is part of the architecture standard
starting in POWER ISA 3, so can be relied upon.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
