PCI: mvebu: Use fixed-width interrupt masks to avoid truncation in 64-bit builds

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.

Fixes below and similar warnings:

  drivers/pci/controller/pci-mvebu.c:316:21: error: implicit conversion from 'unsigned long' to 'u32' (aka 'unsigned int') changes value from 18446744069414584320 to 0 [-Werror,-Wconstant-conversion]
           mvebu_writel(port, ~PCIE_INT_ALL_MASK, PCIE_INT_UNMASK_OFF);
