drm/dp: Bit definition for D3 power state that keeps AUX fully powered
DPCD 600h - SET_POWER & SET_DP_PWR_VOLTAGE defines power state
101 = Set Main-Link for local Sink device and all downstream Sink
devices to D3 (power-down mode), keep AUX block fully powered, ready to
reply within a Response Timeout period of 300us.
This state is useful in a MST dock + MST monitor configuration that
doesn't wake up from D3 state.
v2: Use spaces instead of tabs (Jani)
