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.

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.

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.

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.
