[HACK] drm/exynos: Disable regulators
Currently DRM driver doesn't handle deferred probe properly. If
the regulators are not found during HDMI probe, it doesn't retry
later. Since I2C controller is registered as a module driver, the
PMIC client driver also gets registered later. In current build-order,
DRM drivers are registered before the PMIC driver, hence causing
this failure.
The regulators are always-enabled and the regulator operations
from driver is removed.
