PCI: designware: Move Root Complex setup code to dw_pcie_setup_rc()
dw_pcie_host_init() looks up host bridge resources, ioremaps them, creates
IRQ domains, and enumerates devices below the bridge. dw_pcie_setup_rc()
programs the Root Complex registers. The Root Complex may lose power
during suspend-to-RAM, and when we resume, we want to redo the latter but
not the former.
Move some Root Complex programming from dw_pcie_host_init() to
dw_pcie_setup_rc() where it belongs. DesignWare-based drivers can call
dw_pcie_setup_rc() in their resume paths.
[Niklas Cassel <niklas.cassel@axis.com>: This change moves outbound ATU
programming, which uses pp->mem_base, to dw_pcie_setup_rc(). Apply the
dra7xx pp->mem_base update before calling dw_pcie_setup_rc().]
[bhelgaas: changelog, fold in dra7xx fix from Niklas]
