Realtek card reader supports both SD and MS card. According to the
settings of rtsx MFD driver, SD host will be probed before MS host.
If we boot/reboot Linux with SD card inserted, the resetting flow of SD
card will succeed, and the following resetting flow of MS is sure to fail.
Then MS upper-level driver will ask rtsx driver to turn power off. This
request leads to the result that the following SD commands fail and SD card
can't be accessed again.

In this commit, Realtek's SD and MS host driver will check whether the card
that upper driver requesting is the one existing in the slot. If not, Realtek's
host driver will refuse the operation to make sure the exlusive accessing
at the same time.

set UART_AUX/USB_AUX, micro usb cable is connected to CP(Coprocessor).

When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.

This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.

Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.

Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.

The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

AB8500 GPIO no longer handles its GPIO IRQs. Instead, the AB8500
core driver has taken back the responsibility. Prior to this
happening, the AB8500 GPIO driver provided a set of virtual IRQs
which were used as a pass-through. These virtual IRQs had a base
of MOP500_AB8500_VIR_GPIO_IRQ_BASE, which was passed though pdata.
We don't need to do this anymore, so we're pulling out the
property from the structure.

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.

The failure case is where this unwanted write transfers incorrect data to
a critical register.

This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
