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 5c5f08f7fc0bee9a1bc3fbdcb7a21cfd0648ab14.
