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.

Introduce mt76_mcu data structure to contain common fields between
mt76u_mcu and mt76e_mcu.
Initialize mcu common fields in mt76_alloc_device().
Rely on mt76_mcu in mt76_mcu_rx_event and in mt76_mcu_get_response
in order to reuse them in usb code

Convert mt76_is_mmio and mt76_is_usb to rely on mt76_dev instead of
mt76x02_dev since this is a property not strictly related to hw chipset
and it will be more reusable

MCU request timeout usually indicates that the device is no longer responsive,
and it usually does not recover without a reset

We always wait for CMD_CALIBRATION_OP mcu message, but wait argument is used
for do additional MT_MCU_COM_REG0 register operations, which are needed
for mt76x2e devices and we can use appropriate check instead of wait argument.

Remove wait argument from mt76x02_mcu_set_radio_state and newer wait
for response when sending CMD_POWER_SAVING_OP mcu command.
Note this change behaviour for PCIe devices, but the change is in
align with vendor driver.

Remove wait argument from mt76x02_mcu_function_select and wait for
response when function is not Q_SELECT, what is the same behaviour
like in vendor driver.
Note this change behaviour for PCIe devices for Q_SELECT function
form wait to no-wait, and for mt76x0u BW_SETTING from no-wait to wait.
But the change is in align with vendor driver.

We almost always use patter like this:
skb = mt76_mcu_msg_alloc(dev, &msg, sizeof(msg));
return mt76_mcu_send_msg(dev, skb, CMD_FUN_SET_OP, wait_resp);
This is not needed, we can allocate skb in mcu_send_msg routine.
