The regulator names used for DSS components are somewhat ugly for DT
use. As we're just adding DT support, it's simple to change the
regulator names.
This patch makes the DSS driver get the regulators with somewhat cleaner
names. For example, this allows us to define HDMI's VDDA regulator in
the DT data as:
vdda-supply = <...>;
instead of
vdda_hdmi_dac-supply = <...>;
The code also still tries to get the regulators with the old names, if
the regulator_get with the new names fail. This keep backward
compatibility, and can be removed after we have moved to DT.
