Replace unsigned long with u32 in register accessor functions,
since they access 32bit registers.

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.

This 'shift' is u32 instead of 'unsigned int'.
Rest looks good.

What about converting 'addr' and 'data' here? Other than those, I didn't
find other candidates in this driver.

The MSI address can be 64bit. Switch the data type used to hold the
result of virt_to_phys() to phys_addr_t to reflect its properties
correctly and program the top 32bits of PA into PCIEMSIAUR.
