soc/intel/common/cse: Add function to perform global reset lock

This patch implements `cse_control_global_reset_lock()` as per ME BWG
(doc: 627331) recommendation.

It is recommended that BIOS should set this bit early on in the boot
sequence, and then clear it and set the CF9LOCK bit prior to loading
the OS in both an Intel CSME Enabled and a Intel CSME Disabled system.

Note: For CSE-Lite SKUs BIOS should set CF9LOCK bit unconditionally.

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