DB5500 v1 is no longer supported and now the code makes the
assumption that it runs on hardware revision >= v2. So, lets
deprecate all the v1 codes.

Currently, the eMMC and external SD/MMC card use same
physical channels in the same event group.
This patch moves the SD/MMC card to use a different
eventgroup. There are several cross cases in which both
these are used simultaneously. There seems to be an
improvement in performace of SD card cross use-cases if
these are in different channels.

There is no need to enable the levelshifter in the
MMC_POWER_UP state. Moreover we are not in a stable state
for starting to communicate with the SD-card. Thus we shall
not enable the levelshifter in this state.

The ios_handler may be called several times without a changed
power_mode, thus make sure the power_mode has changed before
we act on it.

The purpose of the vdd_handler does not make sense. We remove it
and use a more generic approach instead. A new "ios" handler is thus
added, the purpose of which e.g. can be to control GPIO pins to
a levelshifter.
Previously the vdd_handler was also used for making additional
changes to the MMCIPOWER register bits. This option is now removed.
This patch is based upon a patch from Sebastian Rasmussen.

mach-ux500: Add SDIO VDD handler for GPIO config
It seems as PL18X does not drive all pins in a correct way when the block
is powered but not initialized. Since CW1200 is sensitive to this (it samples
the DAT2 signal level on bootup to choose between SPI and SDIO mode), it must
be assured that the pins are in a correct state at all times.
This is done by adding a VDD handler for SDI1 which reconfigures all the pins
to GPIO pins with pullups when PL18X is not in an initialized state.

ux500: u8500: Change DMA configuration for SD-card
This patch is a mixture of two earlier patches:
By Sebastian Rasmussen:
ux500: Use other logical DMA channel for SD-card
Previously PoP eMMC SDI has been in the same event group as
SD-card SDI, which means that they have been sharing the
same physical DMA channels. Moreover one of those channels
was reserved for other purposes, causing transfers for each
interface to compete for the same physical DMA channel. In
addition there appears to be a HW issue that causes data to
be lost in the middle of DMA transfers, which ended up with
DMAC and MMCI not agreeing on how much data was still to be
transferred, thereby resulting in a hang and eventually in
a crash.
This patch moves SD-card DMA transfers to another event
group which means that it no longer competes for the same
physical DMA channel. This results in that no data is lost
in the transfers and no hang is observed.
By Rabin Vincent:
ux500: mop500: force SD/MMC and MSP2 TX onto different channels
SD/MMC with event line 1 can be in channel 0 or 1. Force both Rx
and Tx onto channel 0. Both will anyway not used at the same time,
and with this change channel 1 will be available for MSP2 Tx
without sharing.
