[PATCH v15 09/17] PCI: imx6: Call host init function directly in resume

[Richard Zhu]

Call imx6_pcie_host_init() instead of duplicating codes in resume.  Note
that this also means we do MPLL setup again during resume, which we didn't
do before.

[bhelgaas: add MPLL setup note, pointed out by Lucas]
