ASoC: atmel: Fix the 8K sample parameter in I2SC master
The 8K sample parameter of 12.288Mhz main system bus clock doesn't work
because the I2SC_MR.IMCKDIV must not be 0 according to the sama5d2
series datasheet(I2SC Mode Register of Register Summary).
So use the 6.144Mhz instead of 12.288Mhz to support 8K sample.
