soc/intel/common/cse: Perform cse_fw_sync on BS_PRE_DEVICE entry 

This change drops the special check added for TGL/JSL platforms and
performs cse_fw_sync on BS_PRE_DEVICE entry. This was being done later
in the boot process to ensure that the memory training parameters are
written back to SPI flash before performing a reset for CSE RW
jump. With the recent changes in CB:44196 ("mrc_cache: Update
mrc_cache data in romstage"), MRC cache is updated right away in
romstage. So, CSE RW jump can be performed in BS_PRE_DEVICE phase.
