in its suspend and resuse function.On the other hand,firmware stores
GITS_CTRL,GITS_CBASER,GITS_CWRITER and GITS_BASER in the suspend,
and restores these registers in the resume. As a result, the ITS executes
the residual comma

During wakeup, the ATF restore interface restores the values of
the cbaser and cwriter registers. As a result, the ITS executes
the residual commands in the queue, which may cause memory corruption.
To solve this problem, clear all data in the command queue
in the suspend interface of the ITS driv
