soc/intel/{common,skl,cnl,icl,apl,tgl}: Move HFSTS1 register definition to SoC
Below changes are implemented:
1. Move HFSTS1 register definition to SoC since HFSTS1 register definition
is specific to a SoC. Moving structure back to SoC specific to avoid
unnecessay SoC specific macros in the common code.
2. Define a set of APIs in common code since CSE operation modes and
working states are same across SoCs.
cse_is_hfs1_com_normal(void)
cse_is_hfs1_com_secover_mei_msg(void)
cse_is_hfs1_com_soft_temp_disable(void)
cse_is_hfs1_cws_normal(void)
3. Modify existing code to use callbacks to get data of me_hfs1 structure.
TEST=Build and Boot hatch, soraka, tglrvp, bobba and iclrvp boards.
