Liav A 2def16a3d2 Kernel/Graphics: Introduce the IntelDisplayConnectorGroup class 
In the real world, graphics hardware tend to have multiple display
connectors. However, usually the connectors share one register space but
still keeping different PLL timings and display lanes.
This new class should represent a group of multiple display connectors
working together in the same Intel graphics adapter. This opens an
opportunity to abstract the interface so we could support future Intel
iGPU generations.

This is also a preparation before the driver can support newer devices
and utilize their capabilities.
The mentioned preparation is applied in a these aspects:
1. The code is splitted into more classes to adjust to future expansion.
2 classes are introduced: IntelDisplayPlane and IntelDisplayTranscoder,
so the IntelDisplayPlane controls the plane registers and second class
controls the pipeline (transcoder, encoder) registers. On gen4 it's not
really useful because there are probably one plane and one encoder to
care about, but in future generations, there are likely to be multiple
transcoders and planes to accommodate multi head support.
2. The set_edid_bytes method in the DisplayConnector class can now be
told to not assume the provided EDID bytes are always invalid. Therefore
it can refrain from printing error messages if this flag parameter is
true. This is useful for supporting real hardware situation when on boot
not all ports are connected to a monitor, which can result in floating
bus condition (essentially all the bytes we read are 0xFF).
3. An IntelNativeDisplayConnector could now be set to flag other types
of connections such as eDP (embedded DisplayPort), Analog output, etc.
This is important because on the Intel gen4 graphics we could assume to
have one analog output connector, but on future generations this is very
likely to not be the case, as there might be no VGA outputs, but rather
only an eDP connector which is converted to VGA by a design choice of
the motherboard manufacturer.
4. Add ConnectorIndex to IntelNativeDisplayConnector class - Currently
this is used to verify we always handle the correct connector when doing
modesetting.
Later, it will be used to locate special settings needed when handling
connector requests.
5. Prepare to support more types of display planes. For example, the
Intel Skylake register set for display planes is a bit different, so
let's ensure we can properly support it in the near future.
