drm/meson: dw-hdmi: Fix devm_regulator_*get_enable*() conversion againdrm-misc-fixes-2023-03-16
devm_regulator_get_enable_optional() returns -ENODEV if requested
optional regulator is not present. Adjust code for that, because in the
67d0a30128c9 I've incorrectly assumed that it also returns 0 when
regulator is not present.
