ASoC: amd: acp: Set Speaker enable/disable pin through rt1019 codec driver.

RT1019 codec has two ways of controlling the en_spkr.  one way is
controlling through gpio pin method the another way is through codec
register update through driver.

Now Speaker enable/disable is controlled  through codec register updated
by codec driver.  This patch reverts gpio logic.

This reverts commit 5c5f08f7 ("ASoC:
amd: acp: Power on/off the speaker enable gpio pin based on DAPM
callback.")
