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.
