Aseda Aboagye c76f9852c4 cr50: wp: Only use RAM val on wake from hibernate.
When Cr50 resumes from hibernate, it should use the WP state that was
stored in the long life scratch registers.  All other boots should
simply follow the state of the BATT_PRES_L pin.

BUG=b:36659750
BRANCH=master,cr50
TEST=Power on Cr50 via battery, verify that WP_L remains asserted.
