Subject: [PATCH 065/381] ASoC: wm8804: Implement MCLK configuration options,
 add 32bit support WM8804 can run with PLL frequencies of 256xfs and 128xfs
 for most sample rates. At 192kHz only 128xfs is supported. The existing
 driver selects 128xfs automatically for some lower samples rates. By using an
 additional mclk_div divider, it is now possible to control the behaviour.
 This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It
 should allow lower jitter and better signal quality. The behavior has to be
 controlled by the sound card driver, because some sample frequency share the
 same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only
 difference is the MCLK divider.

This also added support for 32bit data.
