Currently MDP driver rejects reusing of a pipe if this reuse results
in wastage of SMPs. i.e. VIG0 pipe reused from YUV layer to RGB layer.
In this case, since RGB layer needs only plane0, plane1 SMPs are unused.
This kind of wasting leads to un-necessary GPU fall-backs for composition
when number of SMPs and number of pipes are less. For this reason driver
used to prohibit such configuration. But in high tier chip-sets, there
are enough number of SMPs and pipes are available such that these
transient wastage of SMPs can be absorbed without much impact.

Whenever the display always-on feature is enabled, it is possible
that the display pipeline can be in an intermediate state between being
fully interactive to fully turned off. In the current implementation, a
number of state transition decisions are made based on whether the
display pipeline is on or not. Instead of explicitly checking for the
panel power state, define generic helper functions which classify the
panel power state into three different stages - interactive, low-power
and off. Replace any existing check for the panel power state with these
newly defined helper functions.

Currently a panel either be in a powered on state or a powered off
state. However, it is possible for panels to be configured in an
intermediate low-power state where the panel is always kept on. In
order to support such use-cases, it is necessary to add the concept
of panel power states in MDSS so that each software layer can
independently maintain it's state and manage transitions between them.
This change just refactors the driver with only two existing power
states - panel on and panel off.

MDSS GDSC can be turned off, or power-collased for command mode panels
in static screen use-cases. In the current implementation, the power
collapse is triggered by a worker thread in the interface driver
whenever it enters the idle state. However, MDP driver already
registers pm_runtime callbacks for idle and suspend notifications and
also maintains a count of active overlay sessions. It is much simpler
and cleaner to trigger idle-power collapse based on that. This also
avoids unnecessary synchronization issues pertaining to the power
collapse worker thread.
