to look at the new patch set (#2).

soc/intel/adl: Remove IOM Mctp command from TCSS ASL
TCSS ASL code was carried forward from TGL and it used to follow the same sequence.
Recently as part of s0ix hang issue, it was found that sending IOM MCTP command as part of TCSS D3 Cold enter-exit sequence created an issue. Due to change in hardware sequence, ADL should not set/reset IOM MCTP Bit during D3 cold entry or exit.
This patch removes the bit setting from ASL file to prevent hang in the system
BUG=b:220796339 BRANCH=firmware-brya-14505.B TEST=Check if hang issue is resolved with the CL and no other regression observed
