mainboard/asus/am1i-a: turn on the tpm
Along with other patches submitted for review to get the chipset parts working, this allows Linux or other OS to use a TPM module plugged into the 20-pin LPC header on the board, by exposing its presence through the ACPI and PNP tables. This patch adds to the Kconfig and devicetree.cb files. Tested with the TPM/FW 3.19 and the trousers tools.
