PCI: imx6: Drop imx6_pcie_wait_for_link()
All calls to imx6_pcie_wait_for_link() share the same error path and
the state of PHY debug registers will already be printed there, so
there's no real reason we can't just use dw_pcie_wait_for_link(). Drop
imx6_pcie_wait_for_link() and replace it with dw_pcie_wait_for_link().
