On some servers there is a hardcoded EDID provided
in the vbios so that the driver will always see a
display connected even if something like a KVM
prevents traditional means like DDC or load
detection from working properly. Also most
server boards with DVI are not actually DVI, but
DVO connected to a virtual KVM service processor.
If we fail to detect a monitor via DDC or load
detection and a hardcoded EDID is available, use
it.
Additionally, when using the hardcoded EDID, use
a copy of it rather than the actual one stored
in the driver as the detect() and get_modes()
functions may free it if DDC is successful.
This fixes the virtual KVM on several internal
servers.

We previously used a static array, but some new systems
had more states then we had array space, so dynamically
allocate space based on the number of states in the vbios.

The general idea is to validate the current hw state
against the set of power states and select a power
state based on that. This patch just pulls the power
states from the bios and prints the information. It
is not currently hooked up in the actual power management
code. Hooking it up will require reworking the the current
power state selection code and will be handled in a future
patch.
Additionally, we'd need to decide on some default lower
power states for cards without power tables.
