chromeos: Unconditionally clear the EC recovery request
Add the empty weak function clear_recovery_mode_switch().
Problem:
If GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC is set,
the following will happen:
1. Boot device in recovery mode with Esc + F3 + Pwr.
2. Turn device off with Pwr button.
3. Turn device on with Pwr button.
Device still boots to recovery screen with
recovery_reason:0x02 recovery button pressed.
If GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC isn't set, turning the
device off and on again with the Pwr button does a normal boot.
Solution:
Unconditionally clear the recovery flag.
BUG=chromium:279607
BRANCH=TOT
TEST=Compile OK.
