soc/intel/common/cse: Rework heci_disable function
This patch provides the possible options for SoC users to choose the
applicable interface to make HECI1 function disable at pre-boot.
`SOC_INTEL_COMMON_BLOCK_HECI_DISABLE_USING_SBI` config is used for
disabling heci1 using non-posted sideband write (inside SMM) after
FSP-S sets the postboot_sai attribute. Applicable from CNL PCH onwards.
`SOC_INTEL_COMMON_BLOCK_HECI_DISABLE_USING_PMC_IPC` config is used for
disabling heci1 using PMC IPC command `0xA9`. Applicable from TGL PCH
onwards.
`SOC_INTEL_COMMON_BLOCK_HECI_DISABLE_USING_PCR` config is used for
disabling heci1 using private configuration register (PCR) write.
Applicable for SoC platform prior to CNL PCH.
Additionally, add PID_CSME0 macro for SKL, Xeon_SP and APL to fix the
compilation failure.
Finally, rename heci_disable() function to heci1_disable() to make it
more meaningful.
BUG=none
TEST=Able to build and boot brya.
