We need the calculate the pixel clock before allocating a PPLL
in order to insure the clocks really match.

If several non-DP displays use the same pixel clock
we can use the same PPLL for all of them. If all
relevant displays have the same pixel clock, this
allows the driver to:
- use fewer PPLLs which saves power
- support more than two non-DP displays on DCE4+
The current drm modesetting infrastructure doesn't
really provide a good framework for validating combinations
that work or won't work, so it's possible you could go from
a working configuration to a non-working one by changing the
mode a one of the displays. However, there this is better
than what was there before.

For DP we can use the same PPLL for all active DP
encoders. Take advantage of that to prevent cases
where we may end up sharing a PPLL between DP and
non-DP which won't work. Also clean up the code
a bit.
v2: - fix missing pll_id assignment in crtc init
v3: - fix DP PPLL check
- document functions
- break in main encoder search loop after matching.
no need to keep checking additional encoders.
v4: - same as v3, but re-apply to drm-next as the corner
cases are fixed properly in subsequent patches.

Roughly based on how nouveau is handling it. Instead of
adding the bo_va when the address is set add the bo_va
when the handle is opened, but set the address to zero
until userspace tells us where to place it.

The AMD ACPI interface may use ACPI_VIDEO_NOTIFY_PROBE to signal SBIOS
requests; block the keypress in this case since the user did not
actually press the mode switch key.

The standard video events may be overloaded for device specific
purposes. For example AMD ACPI interface overloads
ACPI_VIDEO_NOTIFY_PROBE (0x81) to signal AMD-specific events. In such
cases we don't want to send the keypress (KEY_SWITCHVIDEOMODE) to the
userspace because the user did not press the mode switch key (the
spurious keypress confuses the DE which usually changes the
display configuration and messes up a dual-screen setup).
This patch gives the handlers the chance to examine the event and
block the keypress if the event is device specific.
