Subject: [PATCH v3 05/43] drm/bridge: analogix_dp: Don't power bridge in analogix_dp_bind
From: zain wang <wzz@...k-chips.com>
The bridge does not need to be powered in analogix_dp_bind(), so
remove the calls to pm_runtime_get()/phy_power_on()/analogix_dp_init_dp()
as well as their power-off counterparts.

[the patch originally just removed the power_on portion, seanpaul removed
the power off code as well as improved the commit message]
