This converts the Ux500 family to use the pinctrl driver for
configuring pins.

This updates the Ux500 pin handling to take much more care when
applying pin settings for different platforms and peripherals.
This is an accumulation of a longer history of updates to the
MOP500 family pin file.

Implement an API to allow a list of pincfgs to be remuxed to active
and sleep modes, for power saving. This is not exported on purpose,
because it is not to be called by drivers directly.

With bug.h currently living right in linux/kernel.h there
are files that use BUG_ON and friends but are not including
the header explicitly.  Fix them up so we can remove the
presence in kernel.h file.

The <[plat|mach]/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

This sets up a few GPIO pins and some pinmuxing on platform boot
for the Snowball board. Based on work from Mathieu J. Poirier
<mathieu.poirier@linaro.org>.

This patch provides platform data for following
 - uart reset function to assist uart register lockup workaround

 - init/exit function to fix glitch in the tx pin in tty_open
	when tty port0 is opened a glitch is seen in the tx line
	of uart0. This happens in pl011_startup() when tx fifo
	interrupt is provoked into asserting.
	Now uart0 pins are enabled (alt function) only when init
	is complete and turned back to gpio when closed.

This will centralize all GPIO pin muxing for the different boards
in the MOP500 family to a single file. It also kills off the
deprecated support for the ED (Early Drop) ASIC, this should
never be spotted in the open and ST-Ericsson have internally
deprecated this hardware.
