Subject: [PATCH v2 6/6] ASoC: dt-bindings: fsl-sai: Add two PLL clock source

Add two PLL clock source, they are the parent clocks of root clock
one is for 8kHz series rates, another one is for 11kHz series rates.
They are optional clocks, if there are such clocks, then driver
can switch between them for supporting more accurate rates.
