Pardeep Kumar Singla - July 24, 2013, 9:35 p.m.
Instead of duplicating HDMI setup code for every mx6 board, factor out the common code

Signed-off-by: Pardeep Kumar Singla <b45784@freescale.com>
---
Changes since v2:
Added new function enable_ipu_clock() to separate the functinality of ipu clock from hdmi setup.
Remove unnecessary include files.

If this is public, it should be declared in
	arch/arm/include/asm/arch-mx6/clock.h

I think this enabling belongs in the routines which call
imx_setup_hdmi(), since folks will (and probably have) create
custom boards based on those shells and this is also
required to support for LDB and RGB displays.

This is probably where the enable_ipu_clock() call belongs.
