[PATCH v2] drm/tegra: hdmi: probe deferral error reporting

[Marcel Ziswiler <marcel@ziswiler.com>]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Actually report the error code from devm_regulator_get() unless it
is just a probe deferral.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Changes in v2:
- Silence probe deferral as suggested by Lucas.
- Fix line over 80 characters as reported by checkpatch.
