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.

    TEST=Compile OK.
