ASoC: cs4271: Convert to GPIO descriptors
This converts the Cirrus CS4271 ASoC codec driver to use
GPIO descriptors.
It turns out that there are two in-kernel users of the platform
data passing mechanism so these are switched over as well.
One locally defined GPIO "gpio_disabled" is declared in the
state struct but completely unused in the driver, so we delete
it.
