[Maverick][[Pull request] SRU: Fixing display for IGEPv2

[Ricardo Salveti de Araujo]

SRU Justification:

Impact: When booting current omap 3 kernel at an IGEPv2 board the omapdss
subsystem will look for two different regulators, one is "vdda_dac" and the
other is "vdds_sdi". When a regulator is not found the initialisation sequence
is aborted, resulting in omapfb not finding a display to work with.

Fix: The problem is fixed by adding both regulators at the machine description
file, simlilar to what we have for omap3evm, beagleboard and pandaboard. The
first patch was submited upstream already, but it's still not applied. The
second patch follows the same fix created for omap3evm (c97113) for bug 630885
and needs to be tested with upstream before sending it.

Testcase: When booting an IGEPv2 without both patches the screen will fail to
initialize, giving the following errors:
[ 0.735382] omapdss VENC error: can't get VDDA_DAC regulator
[ 0.741363] omapdss CORE error: Failed to initialize venc
...
[ 1.473388] omapfb omapfb: no displays
[ 1.477203] omapfb omapfb: failed to setup omapfb
[ 1.481994] omapfb: probe of omapfb failed with error -22
