[PATCH 2/4] ASoC: dt-bindings: fsl,xcvr: Add two PLL clock sources

[Shengjiu Wang <shengjiu.wang@xxxxxxx>]

Add two PLL clock sources, they are the parent clocks of the root clock
one is for 8kHz series rates, named as 'pll8k', another one is for
11kHz series rates, named as 'pll11k'. They are optional clocks,
if there are such clocks, then the driver can switch between them to
support more accurate sample rates.

As 'pll8k' and 'pll11k' are optional, then add 'minItems: 4' for
clocks and clock-names properties.
