* that we must hand the SSP pins back to the GPIO module before disabling
* the SSP.
*
* In addition, to reduce power drain, we toggle the SFRM line once so
* that the UDA_WS line is at logic 0.
*
* We can't clear ASSABET_BCR_CODEC_RST without knowing if the UCB1300 or
* ADV7171 driver is still active. If it is, then we still need to play
* games, so we might as well leave ASSABET_BCR_CODEC_RST set.
