[RFC][PATCH 1/3] OMAP: DSS2: Do regulator stuff in dpi_init_display()

[Roger Quadros <roger.quadros@nokia.com>]

From: Roger Quadros <roger.quadros@nokia.com>

We don't want dpi_init() to fail in any case as it will prevent us
from using DSS2 if we don't have DSI in the system. This is because
dpi_init() is done unconditionally by the DSS2 core.

We will only need to do regulator initialization when DPI is actually
present in the system. So we do regulator init stuff in dpi_init_display()
