[PATCH v1] platform/x86: pmc_atom: Fix parent clocks

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

PLL or XTAL is a choice of parents. They are not dependent to
each other (direct citation):

	The source of the frequencies can be XTAL or PLL, depending on
	the configuration. Any of the two available frequencies can be
	selected for each of the platform clocks.

According to datasheet on hand CherryTrail has them, though they both
provide 19.2MHz frequency.
