mb/msi/ms7d25,ms7e06: Enable discrete TPM module support
Now that multiple TPM drivers may be compiled in, it is possible to
support switching between fTPM and dTPM.
The patch adds:
- Device tree entry for PC80 discrete TPM
- TPM PIRQ# GPIO active low routed to IOAPIC for TPM interrupt
- MEMORY_MAPPED_TPM option to board's Kconfig to enable PC80 TPM driver
When the ME is disabled, e.g. via HECI command, chipset will route the
TPM traffic to SPI automatically. When a SPI TPM is connected to the
JTPM1 on the board, it will be probed successfully and initialized
in place of inactive PTT/fTPM.
