In preparation for the addition of SPI support for the WM831x move the I2C
specific code into a separate file with a separate Kconfig option so the
I2C support can be excluded from the build.

Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new

The mfd driver for MC13783 recently got support for MC13892 and was
renamed accordingly from mc13783-core to mc13xxx-core.  Do the same for
rtc-mc13783.

The only relevant change is to use platform id's to tell the platform bus
that this driver is responsible for mc13892-rtc devices, too.

Adding card detect callback function and card detect configuration
function for MMC1 Controller on OMAP4.

Card detect configuration function does initial configuration of the
MMC Control & PullUp-PullDown registers of Phoenix.

For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030.

Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect,
the suspend/resume initialization which was done in omap_hsmmc_gpio_init
previously is moved to the probe thus making it generic for both OMAP3 &
OMAP4.

The regulator driver was converted to get the needed data directly from
platform_data by

	a10099bc (regulator/mc13783: various cleanups)

so regulators and num_regulators can go away.  Then apart from the flag
indicating that the adc does a conversion, flags is only a copy of the
flags member of platform_data.  This flag isn't needed to be returned by
mc13783_get_flags, so mc13783_get_flags now gets the flags from
platform_data, too and the driver private member is renamed for clearity.
