ASoC: Intel: bytcr_rt5651: Fix using the wrong GPIO for the ext-amp on some boards

Browse source

Some boards have I2cSerialBusV2, GpioIo, GpioInt as ACPI resources, other
boards may  have I2cSerialBusV2, GpioInt, GpioIo instead. We want the
GpioIo one for the ext-amp-enable-gpio.

So far we've been assuming that the GpioIo one always comes first, this
commit adds code to detect which one comes first and to add the right
gpio-mapping.

This fixes sound not working on the Vios LTH17 laptop.
