PCI: rcar: Replace various variable types with unsigned ones for register values

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