src/soc/intel/common/block/cse: Make hfsts1 common & add helper functions

Host FW status 1 (FWSTS1/HFSTS1) register definition is common across SoCs,
hence move it to common. Also add below helper function,

* wait_cse_sec_override_mode() - Polls ME status for "HECI_OP_MODE_SEC_OVERRIDE".
  It's a special CSE mode, the mode ensures CSE does not trigger any
  spi cycles to CSE region.

* set_host_ready() - Clears reset state from host CSR.

TEST=Verified CSE recover mode on CML RVP & Hatch board
