soc/intel/common: Add function to wait for CSE to enter Soft Temp Disable mode
Below helper function is added:
cse_wait_com_soft_temp_disable() - It polls for CSE's operation mode
'Soft Temporary Disable'. CSE enters this mode when it boots from
RO(BP1) partition. The function must be called after resetting CSE to
wait for CSE to enter 'Soft Temporary Disable' Mode.
