[ Upstream commit 1bb42a354d8ca2888c7c2fcbf0add410176a33dc ]
Fix the false positive suspend error that may occur on mt7921s with enlarging mcu timeout value.
The reason why we have to enlarge mcu timeout from HZ / 3 to HZ is we should consider the additional overhead caused by running concurrently with btmtksdio (a MT7921 bluetooth SDIO driver) that would compete for the same SDIO bus in process context to complete the suspend procedure.
