[PATCH 3/3] drm/msm/dp: Clean up pdev/dev duplication in dp_power

[Bjorn Andersson <quic_bjorande@xxxxxxxxxxx>]

The dp_power module keeps track of both the DP controller's struct
platform_device and struct device - with the prior pulled out of the
dp_parser module.

Clean up the duplication by dropping the platform_device reference and
just track the passed struct device.
