soc/intel/cmn/cse: Move API to get FW partition info into cse_lite.c
The patch moves API that gets the CSE FW partition information into
CSE Lite specific file aka cse_lite.c because the consumer of this API
is the cse_lite specific ChromeOS devices hence, it's meaningful to
move the cse lite specific implementation inside cse_lite.c file.
BUG=b:273661726
TEST=Able to build and boot google/marasov with this code change.
