cr50: Update to VENDOR_CC_GET_PWR_BTN
Change the VENDOR_CC_GET_PWR_BTN behavior to report the live state of
the power button. On Wilco devices, the AP needs to poll for both a
power button press and release prior to booting an untrusted OS.
The falling edge of the power button is still latched, so the first call
to VENDOR_CC_GET_PWR_BTN command will return a button state of 1 if this
call is made within 10 seconds. Once the latched state is clear,
VENDOR_CC_GET_PWR_BTN returns the live state of the power button.
BUG=b:128431787
BRANCH=cr50
TEST=Added test code into vboot recovery screen to poll
VENDOR_CC_GET_PWR_BTN command for a power button press and a power
button release.
