The second SPI controller is wired to the low speed 96boards
connector on Developerbox. SynQuacer platform can exposes
its SPI TPM via MMIO window that is backed by the SPI
command sequencer in the SPI bus controller.
This commit adds the MMIO TPM description to the DSDT.
If TPM2_ENABLE build option is not enabled, existing linux
SPI driver is used instead of MMIO TPM.
