spi: cs42l43: Add GPIO speaker id support to the bridge configuration

Browse source

OEMs can use the spk-id-gpios ACPI property to indicate the type of
speakers fitted to a device.

Attempt to read a spk-id value using the GPIO method when a usable
spk-id value is not obtained from the 01fa-spk-id-val ACPI property.

Obtaining the spk-id value has been moved earlier in the function to the
other sidecar block, so that an -EPROBE_DEFER from a GPIO driver is
handled more efficiently.
