[PATCH 1/3] PCI: rcar: Replace unsigned long with u32 for register values

[marek.vasut@gmail.com]

From: Marek Vasut <marek.vasut+renesas@gmail.com>

Replace unsigned long with u32 type for variables holding
register values, since the registers are 32bit. Note that
rcar_pcie_msi_irq() still uses unsigned long because both
find_first_bit() and __fls() require unsigned long as an
argument.
