dbc2b17647 mt76: Fix undefined behavior due to shift overflowing the constant
Fix:

  drivers/net/wireless/mediatek/mt76/mt76x2/pci.c: In function ‘mt76x2e_probe’:
  ././include/linux/compiler_types.h:352:38: error: call to ‘__compiletime_assert_946’ \
	declared with attribute error: FIELD_PREP: mask is not constant
    _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic for the gory
details as to why it triggers with older gccs only.

fd6c2dfa49 mt76: mt76x02: fix handling MCU timeouts during hw restart
If a MCU timeout occurs before a hw restart completes, another hw restart
is scheduled, and the station state gets corrupted.
To speed up dealing with that, do not issue any MCU commands after the first
timeout, and defer handling timeouts until the reset has completed.
Also ignore errors in MCU commands during start/config to avoid making user
space fail on this condition. If it happens, another restart is scheduled
quickly, and that usually recovers the hardware properly.

In order to improve performances when the system is heavily loaded,
substitute stat_work delayed_work with a regular work_struct and create
a mt76u dedicated workqueue for tx status reporting

f37f055035 mt76: mt76x2e: disable pcie_aspm by default
On same device (e.g. U7612E-H1) PCIE_ASPM causes continuous mcu hangs and
instability. Since mt76x2 series does not manage PCIE PS states, first we
try to disable ASPM using pci_disable_link_state. If it fails, we will
disable PCIE PS configuring PCI registers.
This patch has been successfully tested on U7612E-H1 mini-pice card
