samus: Declare TPM in devicetree.cb and include ACPI device

This adds the TPM device to the devicetree and configures an
active high edge triggered interrupt at IRQ10 and adds the ACPI
Device for the TPM into the DSDT.

It also cleans up the EC PNP ID to use the EISAID for an EC since
there are now two PNP devices declared, and removes the unused
ENABLE_TPM define at the top of the DSDT.

BUG=chrome-os-partner:33385
BRANCH=samus
TEST=build and boot on samus, ensure TPM is functional at IRQ10
