Marcin Bukat 361913fdd2 YP-CP3: make the WM8750 the I2S master 
The WM8750 frames its ADC on ADCLRC and its DAC on DACLRC. As the I2S
slave both are inputs, and the rk27xx has a single LRCK, which on the
YP-CP3 evidently does not reach ADCLRC: with the rk27xx as the master,
the recording DMA got exact zeros on most visits to the recording
screen and real samples only by chance, sometimes changing partway
through a visit. That stays so with the codec PLL no longer glitching
the I2S clocks (previous commit); with the codec as the master it does
not happen.

The codec now drives BCLK and both LRCKs itself, and the rk27xx I2S
transmitter and receiver are slaves. The codec's MCLK still comes from
the rk27xx codec PLL at 256 fs, so sample rates stay exact. The
original firmware runs the codec as master too, but off a fixed 12 MHz
in USB mode.

RK27XX_I2S_MCLK says the rk27xx makes the codec's MCLK, apart from
CODEC_SLAVE, which also makes it the I2S master. The YP-CP3 drops
CODEC_SLAVE for RK27XX_I2S_MCLK, and the WM8750 driver sets its master
bit as it does for any codec that is not a slave.

Tested on a YP-CP3: playback, FM radio, the recording screen's peak
meter on every visit, recording from the microphone and from FM.
