mt76: disable debugfs due to missing piece still in review

Until D57524 is not reviewed and committed we will have a missing
function declaration which prevents us to compile (in) debugfs for
mt76 core and mt7921. Temporary disable debugfs again.

mt76: further adjust debugfs compile time options

The debugfs options between the various modules (core and chipsets)
are not 100% de-coupled. This means we may run into unresolveable
symbols at load time of the modules if we enable certain options
generally or for core but not for the chipset.
For now: always build the core module with debugfs support.
Migrate the CONFIG_MAC80211_DEBUGFS flag into the Makefile of each
chipset so we can individually turn it on.

mt76: mt7921: depend on lindebugfs and turn debugfs support on

Add the missing MODULE_DEPEND() calls for lindebugfs.
It is unfortunate that they are shared code between various bus
implementations.

mt76: mt7921: depend on lindebugfs and turn debugfs support on

Add the missing MODULE_DEPEND() calls for lindebugfs.
It is unfortunate that they are shared code between various bus
implementations. Ideally we would leave the MODULE_DEPEND() calls
in the debugfs.c file instead of adding extra #ifdef guards to the
bus attachment files.

Turn debugfs support on for mt76(core) and the mt7921 module for now.

LinuxKPI wlan drivers: update makefiles to not use WITH_

Up to now the LinuxKPI wlan drivers were using local variables starting
with a WITH_ prefix in their Makefiles.
That is likely to collide with other mechanisms like WITH_ and WITHOUT_
from src.conf.
Adjust the local variables to use a driver name prefix for now to control
what is built and what is not.
These variables are mainly for the time of development so we can
turn off/on a feature or bus attachment while working on it. Otherwise
they are there for documentation purposes. The only reason one would
change them locally would be if someone was to build a very custom
image and not want certain bits (e.g., USB support) being compiled into
the modules.

While here, try to harmonize some parts of the Makefiles.

mt76: sort bus attachments in module Makefiles for pci and usb

With PCI enabled and USB still disabled add knobs to (i) enabled
them manually in the common Makefile.inc and (ii) add bus
attachment depend knobs where needed to enable them in individual
drivers. For now the focus is in 7921 and 7925.

The current version of LinuxKPI lacks support for "page pool" which
needs enhancing and updating a decade or so old shortcut mapping
struct page directly to struct vm_page.
