[PATCH] PCI: rcar-gen4: Inline GIC_TRANSLATER offset macro

[Marek Vasut]

Instead of pulling in the whole linux/irqchip/arm-gic-v3.h , copy the
one GITS_TRANSLATER register offset macro directly into the driver.
This repairs the ability to build the driver on non-ARM non-GIC targets
the way it was possible until now, which retains good build test coverage.

Note: The alternative I could think of would be ifdeffery which
      is not nice and thwarts the build coverage, or limit the
      driver to ARM/ARM64 in Kconfig which also thwarts the build
      coverage. I could also split off the register macros in
      linux/irqchip/arm-gic-v3.h into some separate header
      linux/irqchip/arm-gic-v3-regs.h and include that which
      might be OKish and avoids duplication. Thoughts ?
