mb/google,samsung/*: Add LPC TPM chip driver to devicetree

With commits 9987534 [southbridge/intel: Remove leftover TPM ACPI code]
and 66ce18c [soc/intel: Remove legacy static TPM asl code] removing
TPM ASL code from the southbridge's LPCB device, the LPC TPM chip driver
(drivers/pc80/tpm) must be added to devicetree in order to ensure the
new acpigen code is used to replace it.

Test: boot various google/samsung boards, verify SSDT created with 
LPBC.TPM device and TPM visible to and usable by SeaBIOS and Linux
