Mostly boardfiles in arch/arm and arch/mips do this thing, by way of
the old API using global numbers (that get translated into descriptors).

You can't even blame them: when some of the code was written,
there was no gpio_request() even. David Brownell added that in a
generic way 2008.

We are doing away with it, one driver at a time, one board at a time.

I think I finally purged it from all OMAP boards in v6.7-rc1!
