[ALSA] ASoC: Add WM8510 driver
The WM8510 is a mono CODEC with speaker driver optimised for telephony applications, featuring: - 16/20/24/32 bit audio at data rates between 8kHz and 48kHz - On-chip PLL - Dual microphone inputs This driver was originally written by Liam Girdwood with updates from Brett Saunders, Geoffrey Wossum and myself.
