[PATCH] PCI: mvebu: Use fixed-width interrupt masks

[Rosen Penev]

Use u32-typed BIT and GENMASK helpers for PCIe interrupt register
masks.  This keeps inverted masks in the same width as the registers
and avoids truncation warnings on 64-bit compile-test builds.

Drop the unused sys_to_pcie() helper while touching the same area; it
references stale ARM pci_sys_data glue and has no callers.
