PCI: dwc: Restore MSI Receiver mask during resume
If a host that uses the IP's integrated MSI Receiver lost power
during suspend, we call dw_pcie_setup_rc() to reinit the RC. But
dw_pcie_setup_rc() always sets pp->irq_mask[ctrl] to ~0, so the mask
register is always set as 0xffffffff incorrectly, thus the MSI can't
work after resume.
Fix this issue by moving pp->irq_mask[ctrl] initialization to
dw_pcie_host_init() so we can correctly set the mask reg during both
boot and resume.
