ASoC: rt5640: Convert to just use GPIO descriptors
The RT5640 driver is already using GPIO descriptors for some
stuff, all that is needed is to convert the remaining LDO1
control line to also use descriptors.
Simplify the code using gpiod_get_optional() and drop the
special "of" parsing function: these descriptors need not
come from device tree and it's optional so hey.
Keep some NULL checks around the GPIO operations even though
gpiolib is essentially NULL-tolerant, because by checking
for whether we have a valid GPIO descriptor or not we can
avoid a 400 ms delay which is great.
