soc/intel/tigerlake: Remove IOM Mctp command from TCSS ASL
Port fix from Alder Lake to not set/reset IOM MCTP during D3 cold entry or exit.
Ports 5008d340033d ("soc/intel/adl: Remove IOM Mctp command from TCSS ASL"):
``` 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.
We discovered that due to change in hardware sequence, ADL should not set/reset IOM MCTP during D3 cold entry or exit. This patch removes the bit setting from ASL file to prevent hang in the system.
This patch also removes obsolete Pcode mailbox communication which is no longer required for ADL.
BUG=b:220796339 BRANCH=firmware-brya-14505.B TEST=Check if hang issue is resolved with the CL and no other regression observed
