dm: TPM2 passthrough for post-launched VM with eventlog support

Browse Source 
This patch enables TPM2 passthrough to post-launched VM with eventlog
support.
User starts by providing command line "--acpidev_pt <TPM2_HID>",
of which the <TPM2_HID> will be searched from /proc/iomem for TPM2 buffer
start address and size. Furthermore, If TPM2 eventlog is supported,
TPM2 eventlog information will be retrieved from sysfs TPM2 table and
passed-through as well.

v4 -> v5:
move tpm2 related logic from acpi.c to tpm.c
multiple API rename
