devconf1 reg access is localized only in mach-omap2 and we need to export updating of devconf1 from omapdss venc driver (bypass and acbias bits). Add simple api call which update only necessary bits.

If this is truly a pinmux, you could already access this using pinctrl-single,bits device tree driver. But I guess that won't work yet, so it's best to set this up as a separate driver like we've done for the USB PHY registers. Regards, Tony
