ASoC: codec: wcd9335: Convert to GPIO descriptors

Browse Source 
[ Upstream commit d5099bc1b56417733f4cccf10c61ee74dadd5562 ]

of_gpio.h is deprecated, update the driver to use GPIO descriptors.
- Use dev_gpiod_get to get GPIO descriptor.
- Use gpiod_set_value to configure output value.

With legacy of_gpio API, the driver set gpio value 0 to assert reset,
and 1 to deassert reset. And the reset-gpios use GPIO_ACTIVE_LOW flag in
DTS, so set GPIOD_OUT_LOW when get GPIO descriptors, and set value 1 means
output low, set value 0 means output high with gpiod API.

The in-tree DTS files have the right polarity set up already so we can
expect this to "just work"
