PCI: imx6: Move imx6_pcie_reset_phy() near other PHY handling functions
Move imx6_pcie_reset_phy() near the other PHY related functions in the
file. This is a cosmetic change, but also allows to do the following
changes without introducing needless forward declarations.
[Andrey Smirnov: port to Barebox codebase]
