commit 200a575b68d2 ("ARM: dts: meson: organize devices in their corresponding busses")
organized all peripherals in busses so that the base register offset of
the bus doesn't have to be included in all child-nodes anymore.
The GPIO interrupt controller however specifies the register offset
without subtracting the "cbus" base address. This leads to a problem
where of_iomap inside the irq-meson-gpio driver fails because it
actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880
for the GPIO interrupt controller). Fix this by using 0x9880 as register
offset.
