[PATCH] mfd/db8500-prcmu: remove support for early silicon revisions

From: Linus Walleij <linus.walleij at linaro.org>

The DB8500 ED (Early Drop) and V1 are only available inside of
ST-Ericsson or partners, we have actively replaced and scrapped
these prototypes. All Nova products on the open market (such as
the Snowball board) are based on V2 and later ASIC variants.
So let us focus on supporting the silicon that will be used and
delete this to get a clear overview.

Hi ARM-SoC guys, can either of you please merge this patch to
wherever the other ux500 patches are pending? There is some
cross-dependence on the MFD core and I intended to include this
patch in the original pull request, but I screwed up, breaking
linux-next. Thanks.
