ASoC: add GPIOLIB_LEGACY dependency where needed

ASoC: add GPIOLIB_LEGACY dependency where needed

In order to make the legacy gpiolib interfaces such as gpio_request()
optional, mark the three ASoC driver that rely on it today with a
dependency on the new Kconfig symbol.

The tlv320dac33 and ak4641 drivers have no in-tree users, while the
uda1380 driver is theoretically referened by two lpc3250 based boards,
but neither of them work because of the legacy gpiolib dependency.
