ASoC: UDA134x: Remove POWER_OFF_ON_STANDBY define.

Define POWER_OFF_ON_STANDBY cause trobles when trying to get some
sound from codec because code for bias setup was not compiled
(define wasn't defined). This define was removed in commit:
9cd3607a but again introduced by commit: 41912c7f6 which then
completely break codec functionality so remove it again.
