ASoC: tas5086: Convert to GPIO descriptors

Switch the driver to use GPIO descriptors.

Notice that we let the gpiolib handle line inversion for the
active low reset line (nreset !reset).

There are no upstream device trees using the tas5086 compatible
string, if there were, we would need to ascertain that they all
set the GPIO_ACTIVE_LOW flag on their GPIO lines.
