Subject: [PATCH 220/454] Revert downstream wm8804 changes
The format change from S24_LE to S24_3LE effectively disables 24-bit
mode as S24_3LE isn't supported by bcm2835-i2s. This causes issues
with drivers that want to use wm8804 in 24-bit mode.
Adding the S32_LE format is also incorrect, according to the datasheet
only 16-24 bit formats are supported.
