Decouple the HSMMC glue from the twl4030 as the only
regulator provider, using the regulator framework instead.
This makes the glue's "mmc-twl4030" name become a complete
misnomer ... this code could probably all migrate into the
HSMMC driver now.

Tested on 3430SDP (SD and low-voltage MMC) and Beagle (SD),
plus some other boards (including Overo) after they were
converted to set up MMC regulators properly.

Eventually all boards should just associate a regulator with
each MMC controller they use.  In some cases (Overo MMC2 and
Pandora MMC3, at least) that would be a fixed-voltage regulator
with no real software control.  As a temporary hack (pending
regulator-next updates to make the "fixed.c" regulator become
usable) there's a new ocr_mask field for those boards.

Convert the board-rx51 smc91x code to be generic and make

Add generic onenand support when connected to GPMC and make the
boards to use it.

The patch has been modified to make it more generic to support all
the boards with GPMC. The patch also remove unused prototype for
omap2_onenand_rephase(void).

Note that board-apollon.c is currently using the MTD_ONENAND_GENERIC
and setting the GPMC timings in the bootloader. Setting the GPMC
timings in the bootloader will not allow supporting frequency
scaling for the onenand source clock.

The address range size calculation inside local_flush_tlb_kernel_range()
is being truncated by a too small size variable holder on 64-bit systems.
The truncated size can result in an erroneous tlbsize check that means we
sit spinning inside a loop trying to flush a hige number of TLB entries.
This is for all intents and purposes a system hang. Fix by using an
appropriately sized valiable to hold the size.

[Ralf: Greg's original patch submission identified the issue and fixed one
instance in tlb-r4k.c but there there were several more.  For consistency
I also modified tlb-r3k.c even though that file is only used on 32-bit.]
