cr50: add a closed loop reset function
Add a function that asserts EC_RST_L until TPM_RST_L gets asserted.
Disable sleep using SLEEP_MASK_AP_RUN while waiting for the AP reset.
Disable tpm communications using tpm_stop until the AP is reset.
BUG=b:123544145
BRANCH=cr50
TEST=run 'ecrst cl' on mistral, scarlet, and soraka. Make sure the
sleepmask is cleared correctly and the TPM works after the reset is
complete.
