[PATCH 1/1] ARM: OMAP: board-4430sdp: Provide regulator to pwm-backlight

[Andrew Chew <achew@nvidia.com>]

The pwm-backlight driver now takes a mandatory regulator that is gotten
during driver probe.  Initialize a dummy regulator to satisfy this
requirement.

This patch, along with many more soon to follow, attempts to satisfy the new
mandatory regulator that pwm-backlight will grab during probe.  The only
board in mach-omap2 to use the pwm-backlight appears to be the 4430sdp.

I thought I'd start small and use this board as an example.

I tested similar code in my Tegra board, so it should be okay.  Of course,
I don't have a 4430sdp to test with.
