Get the ack for the command then wait for the scratch register to

[Why]
PSP doesn't have the ability to store SRM in a non-volatile memory. And since
the kernel cannot write to the storage directly, we need usermode to facilitate
this
As per spec the SRM needs to be persistent so this interface is to be
called by the usermode anytime the system goes down/powers on
*boot/resume: load from storage
*shutdown/suspend: save to storage
[How]
Provide a sysfs interface so that the usermode can set/get srm at the right times
save to storage: call "cat /sys/class/drm/card0/device/hdcp_srm > file" after boot and resume
-driver calls psp_get_srm() to get the stored srm and outputs it
load from storage: call "cat file > /sys/class/drm/card0/device/hdcp_srm" before shutdown and suspend
-driver reads the file from sysfs and calls psp_set_srm() to send the SRM to PSP
