Revert "ASoc: rt5639: Set audio CODEC IRQ as a wake up pin"

This reverts commit 125d842fbf3f080c6242f283827a11bf5761e0f4.
dev fails to enter Lp0 due to some buggy codes in kernel.
We have fix for it (http://git-master/r/#/c/487966), but it risky
to OTA 1.1 release. Hence revert it first.

Bug 1545184
