ASoC: pcm512x: Fix not setting word length if DAIFMT_CBS_CFS

Browse source

In `pcm512x_hw_params()`, the following switch-case:

~~~~
	switch (pcm512x->fmt & SND_SOC_DAIFMT_MASTER_MASK) {
	case SND_SOC_DAIFMT_CBS_CFS:
~~~~

returns 0, which was preventing word length from being written into codecs
register.

Fixed by writing it into register before checking
`SND_SOC_DAIFMT_MASTER_MASK`.
Tested with Raspberry Pi + sound card `hifiberry_dacplus` in CBS_CFS format
