ARM: mxs: allow boards to select DC-DC switching clock source
For some board designs, it might be useful to switch the DC-DC
clock source to something else rather the default 24 MHz, e.g.
for EMI reasons.
For this, override the mxs_power_setup_dcdc_clocksource function
in your board support files.
Example:
void mxs_power_setup_dcdc_clocksource(void)
{
mxs_power_switch_dcdc_clocksource(POWER_MISC_FREQSEL_20MHZ);
}
