[PATCH v2] PCI: designware: move remaining rc setup code to dw_pcie_setup_rc()

dw_pcie_setup_rc(), as its name indicates, setups the RC. But current
dw_pcie_host_init() also contains some necessary rc setup code.

Another reason: the host may lost power during suspend to ram, the RC
need to be re-setup after resume. The rc can't be correctly resumed
without the rc setup code in dw_pcie_host_init().

So this patch moves the code to dw_pcie_setup_rc() to address the above
two issues. After this patch, each pcie designware driver users could
call dw_pcie_setup_rc() to re-setup rc when resume back.

Seems reasonable. Thanks for the cleanup. :-)
