Remove OTP calls on wake-up from PhoneWindowManager

OTP is now invoked on every wake-up from HdmiControlService, in response to an ACTION_SCREEN_ON broadcast.
Therefore the explicit call to OTP on wake-up is redundant.

OTP still needs to be invoked explicitely on a HOME button press, since that doesn't always result in wake-up.

Bug: 167961841
Test: atest HdmiCecLocalDevicePlaybackTest and manual tests that wake keys and power button still trigger OTP.
