soc/intel/common/cse: Add `cse_send_end_of_post()` a public function

This patch creates a global function `cse_send_end_of_post()` so
that IA common code may get access to this function for sending EOP
command to the HECI1/CSE device.

Additionally, use static variable to track and prevent sending EOP
command more than once in boot flow.

BUG=b:211954778
TEST=Able to build and boot Brya.
