arm64: dts: imx8mq: assign PCIe clocks
This fixes multiple issues with the current non-existent PCIe clock setup: The controller can run at up to 250MHz, so use a parent that provides this clock. The PHY needs an exact 100MHz reference clock to function if the PCIe refclock is not fed in via the refclock pads. While this mode is not supported (yet) in the driver it doesn't hurt to make sure we are providing a clock with the right rate. The AUX clock is specified to have a maximum clock rate of 10MHz. So the current setup, which drives it straight from the 25MHz oscillator is actually overclocking the AUX input.
