sc7180: Fix DDR training failure during warm reset with OTA

Problem: OTA is triggering warmboot, where DDR is
in self-refresh mode. Due to which DDR training
is not going well.

Change: Verify reboot type in case of OTA. If it is warmboot, will
force for cold boot inorder to trigger DDR training

BUG=b:236990316
TEST=Validated on qualcomm sc7180 development board.

Test observation: Cold boot is triggered forcefully,
if current reboot is warmboot in case of OTA
