soc/intel/common: Rename functions for consistent naming
Below changes are done:
1. Rename below functions to have consistent naming:
set_host_ready() -> cse_set_host_ready()
wait_cse_sec_override_mode() -> cse_wait_sec_override_mode()
send_hmrfpo_enable_msg() -> cse_hmrfpo_enable()
send_hmrfpo_get_status_msg() -> cse_hmrfpo_get_status()
2. Additional debug messages are added in cse_wait_sec_override_mode().
TEST=Build and Boot hatch board.
