Subject: [PATCH] drm: bridge: tc358775: Fix Regulator Names

Drop the -supply suffix from the regulator names inside the
probe function. devm_regulator_get() expects property names without
-supply and will automatically append them.

This fixes:
[...] tc358775 0-000f: supply vddio-supply not found, using dummy regulator
[...] tc358775 0-000f: supply vdd-supply not found, using dummy regulator
