cr50: Add VENDOR_CC_GET_PWR_BTN to query power button
Add the new TPM command VENDOR_CC_GET_PWR_BTN used to query whether
there has been a recent (within 10 seconds) power button press by the
user. This is used by coreboot on Sarien/Arcada to confirm user
presence prior to enabling developer mode and prior to launching closed
source diagnostics.
BUG=b:119346609
BRANCH=cr50
TEST=make buildall. Tested power button query from coreboot recovery
screen screen on Arcada and Sarien platforms.
