arm: qca: Add support to set CRASHDUMP RESET bit

Browse source 
The CRASHDUMP RESET bit of TCSR_BOOT_MISC_DETECT Register
has to be set in the crashdump collection path before reset
from u-boot for the  TZ to differentiate between the
normal reset and crashdump reset from u-boot and
to retain the crash reason.
