ASoC: uda1380: Modernize the driver
This codec driver depended on the legacy GPIO API, and nothing
in the kernel is defining the platform data, so get rid of this.
Two in-kernel device trees are defining this codec using
undocumented device tree properties, so support these for now.
The same properties can be defined using software nodes if board
files are desired. The device tree use the "-gpio" rather than
"-gpios" suffix but the GPIO DT parser will deal with that.
Since there may be out of tree users, migrate to GPIO descriptors,
drop the platform data that is unused, and assign the dac_clk the
value that was used in all platforms found in a historical dig,
and support setting the clock to the PLL using the undocumented
device tree property.
Add some menuconfig so the codec can be selected and tested.
