[PATCH v15 01/17] PCI: imx6: Move imx6_pcie_grp_offset(), imx6_pcie_configure_type() earlier

[Richard Zhu]

From: Bjorn Helgaas <bhelgaas at google.com>

Move imx6_pcie_grp_offset() and imx6_pcie_configure_type() earlier in the
file since they depend on nothing and are used by several other functions
that will be moved earlier.  No functional change intended.
