With TWL6030-usb, VBUS SESS_VLD and SESS_END events are not generated
as expected. When these interrupts are enabled, charger VBUS detection
interrupt does not get generated. So USBOTG has to be dependent on charger
VBUS interrupts.
So added one bit for USBOTG and changed the handler to call the
USBOTG handler whenever there is a charger VBUS interrpt.
VBUS SESS_VLD and SESS_END event generation issue is under debug with
HW team. This fix might not be required once after fixing the issue.

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
a10099b (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.
