[PATCH v1 2/3] PCI: imx6: move the wait for clock stabilization to enable ref clk

[Stefan Eichenberger <eichest@gmail.com>]

From: Stefan Eichenberger <stefan.eichenberger@toradex.com>

After enabling the ref clock, we should wait for the clock to stabilize.
To eliminate the need for code duplication in the future, move the
usleep to the enable_ref_clk function.
