siemens/mc_apl2: Activate TPM support
The TPM chip is connected to the SPI interface of APL. The proper chip select pin needs to be used in order to access the TPM in the memory mapped space. This needed chip select is internally (inside APL) routable to GPIO 106. Therefore the change of GPIO 106 mode is needed to make the TPM work on SPI bus. TEST=Build coreboot for mc_apl2 board and check the TPM console output. In addition the TPM was correctly verified by our Linux driver.
