purism/librem_skl: Enable TPM support

Change the GPIO to match the TPM-enabled motherboards, and add TPM
support in devicetree and enable the config.
After changing the GPIO table, the librem 13v2 and librem 15v3 now
have the same GPIOs, so use a single gpio.h file instead of one
file per variant.
