soc: mediatek: pwrap: Use readx_poll_timeout() instead of custom function
Function pwrap_wait_for_state() is a function that polls an address through a helper function, but this is the very same operation that the readx_poll_timeout macro means to do. Convert all instances of calling pwrap_wait_for_state() to instead use the read_poll_timeout macro.

OK, I'm updating the regression status:
#regzbot introduced: 18c7deca2b8125
And for replying, don't top-post, but rather reply inline with appropriate context instead; hence I cut the replied context.
There are two possible solutions to that, specifically, either: 1. Change readx_poll_timeout() to readx_poll_timeout_atomic(); or 2. Fix the mt6323-led driver so that this operation gets done out of atomic context, which is IMO the option to prefer.
Ideas?
