soc/intel/common/tcss: Move AUX bias ctrl reg defines to SOC hdr
These field defines are SOC-specific. The AUX bias virtual wire field
positons are shifted in PTL.
In MTL SOC and older:
7:0 GROUP_ID Group ID in PCH GPIO
10:8 BIT_NUM Data bit Position in PCH GPIO
23:16 VW_INDEX VW Index in PCH GPIO
In PTL SOC:
15:0 GROUP_ID Group ID in PCH GPIO; targeted SB_PORTID
18:16 BIT_NUM Data bit Position in PCH GPIO
31:24 VW_INDEX VW Index in PCH GPIO
BUG=361048817
TEST=boot to OS and use iotools to read AUX Bias Ctrl register to
verify the group ID, bit number, and vw index.
