0e19942e6d wifi: mt76: mt7925e: fix too long of wifi resume time 
The mt7925e takes a long time to resume in platform resume
scenarios. This is due to the mt7925 reconfiguring the tx
power for each wifi channel during resume. By streamlining
the process and removing redundant power configurations,
the resume time for the mt7925 can be shortened.

8f6571ad47 wifi: mt76: mt7925: add handler to hif suspend/resume event 
When the system suspend or resume, the WiFi driver sends
an hif_ctrl command to the firmware and waits for an event.
Due to changes in the event format reported by the chip, the
current mt7925's driver does not account for these changes,
resulting in command timeout. Add flow to handle hif_ctrl
event to avoid command timeout. We also exented API
mt76_connac_mcu_set_hif_suspend for connac3 this time.

a0f721b8d9 wifi: mt76: mt7925: fix CLC command timeout when suspend/resume 
When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.

Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

1b97fc8443 wifi: mt76: mt7925: fix the unfinished command of regd_notifier before suspend 
Before entering suspend, we need to ensure that all MCU command are
completed. In some cases, such as with regd_notifier, there is a
chance that CLC commands, will be executed before suspend.

8ad8b8c2dc wifi: mt76: mt7925: replace zero-length array with flexible-array member 
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1],
introduced in C99:

struct foo {
	int stuff;
	struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last, which is beneficial
to cultivate a high-quality code.[2]

This issue was found with the help of Coccinelle.

50f64e4253 wifi: mt76: do not hold queue lock during initial rx buffer alloc 
In dma init or reset scene, full buffer is needed for all rx rings. Since
this is very time consuming, split the function to perform initial
allocation without holding the spinlock. This avoids causing excessive
scheduler latency.
