wifi: mt76: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert the three mt76 drivers from always returning zero in
the remove callback to the void returning variant.

wifi: drivers: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

wifi: mt76: mt7915: add support for MT7981

Add support for the MediaTek MT7981 SoC which is similar to the MT7986
but with a newer IP cores and only 2x ARM Cortex-A53 instead of 4x.
Unlike MT7986 the MT7981 can only connect a single wireless frontend,
usually MT7976 is used for DBDC.

wifi: mt76: mt7915: expose device tree match table

On MT7986 the WiFi driver currently does not get automatically loaded,
requiring manual modprobing because the device tree compatibles are not
exported into metadata.

Add the missing MODULE_DEVICE_TABLE macro to fix this.
