[PATCH] omap3: Adding vdd_sdi regulator supply to OMAP3EVM

[Bryan Wu]

From: Mathieu J. Poirier <mathieu.poirier at canonical.com>

https://bugs.launchpad.net/bugs/630885

When booting, the omapdss subsystem is looking for a regulator named
"vdds_sdi". When the regulator is not found the initialisation sequence
is aborted resulting in omapfb not finding a display to work with.  This
patch allows the omapfb sub system to complete its initialisation
properly and enable LCD display. The problem was fixed by lumping a
"vdds_sdi" with the already existing "vdds_dsi" regulator. This fix
takes its root from work done on the Beagle board and the Pandora board.
