Introduce p2p-go/p2p-client support to mt7921 driver

CONNECTION_P2P_GC/GO is not supported with the current firmware
so we added mt76_dev to mt76_connac_mcu_sta_basic_tlv signature to
use CONNECTION_INFRA_STA/AP instead for p2p-client and p2p-go
respectively to make it work.

Zero-length arrays as fake flexible arrays are deprecated and we are
moving towards adopting C99 flexible-array members instead.

Address the following warnings found with GCC-13 and
-fstrict-flex-arrays=3 enabled:
drivers/net/wireless/mediatek/mt76/mt7921/acpi_sar.c:266:25: warning: array subscript 0 is outside array bounds of ‘struct mt7921_asar_dyn_limit_v2[0]’ [-Warray-bounds=]

Notice that the DECLARE_FLEX_ARRAY() helper allows for flexible-array
members in unions.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].

Issue: Though the Netgear AXE3000 (A8000) is based on the mt7921
chipset because of the unique USB VID:PID combination this device
does not initialize/register. Thus making it not plug and play.

Fix: Adds support for the Netgear AXE3000 (A8000) based on the Mediatek
mt7921au chipset. The method of action is adding the USD VID/PID
pair to the mt7921u_device_table[] array.

from lsusb D 0846:9060 NetGear, Inc. Wireless_Device. This pair

In system warm reboot scene, due to the polling timeout(now 1000us)
is too short to wait dma idle in time, it may make driver probe fail
with error code -ETIMEDOUT. Meanwhile, we also found the dma may take
around 70ms to enter idle state. Change the polling idle timeout to
100ms to avoid the probabilistic probe fail.

Tested pass with 5000 times warm reboot on x86 platform.
