The PFC driver causes the kernel to hang on the R-Car gen2 SoC based boards
when the CPU_ALL_PORT() macro is fixed to reflect the reality, i.e. when the
GPIO space becomes actually sparse. This happens because the _GP_GPIO() macro
includes an indexed initializer which causes the "holes" (array entries filled
with all 0s) between the groups of the existing GPIOs; and the driver can't
cope with that. There seems to be no reason to use the indexed initializer,
so we can remove the index specifier and so avoid the "holes".

Hi Sergei,
Thank you for the patch.

I initially thought that this patch looked too good to be true. The fix is so
simple, there must have been a reason why _GP_GPIO used indexed initializers.
I then tried to find that reason and failed.
I still feel that this is too simple to be true, but I have no objective
reason to push back, so

for the whole series, provided you have tested it, and paid attention to pins
after the holes.

On r8a7791/koelsch, the switches (gpio banks 5 and 7) and LEDs (gpio bank 2)
still work, so
