regulator: fixed: Convert to use GPIO descriptor only
As we augmented the regulator core to accept a GPIO descriptor instead of a GPIO number, we can augment the fixed GPIO regulator to look up and pass that descriptor directly from device tree or board GPIO descriptor look up tables. Some boards just auto-enumerate their fixed regulator platform devices and I have assumed they get names like "fixed-regulator.0" but it's pretty hard to guess this. I need some testing from board maintainers to be sure. Other boards are straight forward, using just plain "fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the device ID. The OMAP didn't have proper label names on its GPIO chips so I have fixed this with a separate patch to the GPIO tree, see commit 088413bc0bd5f5fb66ca22a19d66a49d7154ba4c "gpio: omap: Give unique labels to each GPIO bank/chip" It seems the da9055 and da9211 has never got around to actually passing any enable gpio into its platform data (not the in-tree code anyway) so we can just decide to simply pass a descriptor instead. The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named "*_dummy_supply_device" while it is a very real device backed by a GPIO line. There is nothing dummy about it at all, so I renamed it with the infix *_regulator_* as part of this patch set. For the patch hunk hitting arch/blackfin I would say I do not expect testing, review or ACKs anymore so if it works, it works. The hunk hitting the x86 BCM43xx driver is especially tricky as the number comes out of SFI which is a mystery to me. I definately need someone to look at this. (Hi Andy.)
