This patch replaces the usage of GPR (General Purpose Registers) like
ECX and EBX for backing up data way and non-eviction mask with SPR
(Special Purpose Registers) EDI and ESI.
Purpose of this change is to ensure the safety while developers might
use ECX often while doing rdmsr/wrmsr rather than making use of EDI.
TEST=Able to boot JSL and TGL platform without any hang using eNEM.

IOMMU spec v3 section 5.2.2.1 all possible device IDs must be defined,
whether the device ID is actually populated or not. Device entries are
used to report ranges when hot-plug and SR-IOV devices are possible.

This patch adds functionality to attempt to allow booting in a secure
configuration (albeit with potentially reduced functionality) when the
CSE EOP message fails in any way. These steps come from the CSME BWG
(13.5, 15.0, 16.), and tell the CSE to disable the MEI bus, which
disables further communication from the host. This is followed by
requesting the PMC to disable the MEI devices. If these steps are
successful, then the boot firmware can continue to boot to the
OS. Otherwise, die() is called, prefering not to boot over leaving the
insecure MEI bus available.
