Subject: [PATCH RESEND2 v4 2/2] drm/meson: dw-hdmi: Use
devm_regulator_*get_enable*()
Simplify using the devm_regulator_get_enable_optional(). Also drop the
now unused struct member 'hdmi_supply'.

v4 resend 2:
Respinning unchanged code with the commit title changed as wa suggested
by Robert Foss and commit message changed as was suggested by Martin.
I am doing a clean-up for my local git and encountered this one.
Respinning as it seems this one fell through the cracks.
