When I posted the same patch for smdk5250, you asked me to club all
the same supply regulators. So I clubbed AVDD2 and CPVDD. So any other
better name for representing both supplies?

As per schemata, input clock to MCLK1 is an oscillator clock with
16.9MHz and MCLK2 not showing any input clock. So here I need to add a
fixed rate clock with 16.9MHz as MCLK1 in the smdk board file.
Is it correct?
Thanks
