Subject: [PATCH v4 07/11] ASoC: jz4740-i2s: Make the PLL clock name SoC-specific

On some Ingenic SoCs, such as the X1000, there is a programmable
divider used to generate the I2S system clock from a PLL, rather
than a fixed PLL/2 clock. It doesn't make much sense to call the
clock "pll half" on those SoCs, so the clock name should really be
a SoC-dependent value.
