I was trying to fix the error handling part because in the case of
request_irq failure, it should call kthread_stop instead of free_irq.
But it seems more reasonable to do request_irq before calling kthread_run.

The charger fault IRQs from the twl will in future patches be handled
by a seperate IRQ handler in the charger driver than the general charger
IRQ. Give them different IRQ numbers now to allow the charger driver to
be merged in the future.

irq_desc checking in the interrupt demux routine is totally
pointless. The driver sets those lines up, so that cant go away
magically.
Remove the open coded handler magic and use the proper accessor.
This driver needs to be converted to threaded interrupts and buslock.

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.

This patch adds support for phoenix interrupt framework. New iInterrupt
status register A, B, C are introduced in Phoenix and are cleared on write.
Due to the differences in interrupt handling with respect to TWL4030,
twl6030-irq.c is created for TWL6030 PMIC
