[Why]
The pointer for integrated_info can be NULL which causes the system to
do a null pointer deference and hang on boot.
[How]
Add a check to ensure that integrated_info is not null before enabling
DP ss.

[why]
Prevent clock source sharing between HDMI and DP connectors.
DP shouldn't be sharing its ref clock with phy clock,
which caused an issue of older ASICS booting up with multiple
diplays plugged in.
[how]
Add an extra check that would prevent HDMI and DP sharing clk.

[Why]
The calculated values for actual disp_clk_khz were ignored when
notifying pplib of the new display requirements. In order to honor DFS
bypass clocks from the hardware, the calculated value should be used.
[How]
The return value for set_dispclk is now assigned back into new_clocks
and correctly carried through into dccg->clks.phyclk_khz. When notifying
pplib of new display requirements dccg->clks.phyclk_khz is used
instead of dce.dispclk_khz. The value of dce.dispclk_khz was never
explicitly set to anything before.
A 15% higher display clock value than calculated is no longer requested
for dce110 since it now makes use of the calculated value.
Since dce112 makes use of dce110's set_bandwidth but not its
update_clocks it needs to have the value correctly carried through.

The DRM mode's HDMI picture aspect ratio field was never saved in

[Why]
Some boards seem to have a problem where HPD is high on HDMI even though
no display is connected. We don't want to report these as connected. DP
spec still requires us to report DP displays as connected when HPD is
high but we can't read the EDID in order to go to fail-safe mode.
[How]
If connector_signal is not DP abort detection if we can't retrieve the
EDID.

idx can be indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:408 amdgpu_set_pp_force_state()
warn: potential spectre issue 'data.states'
Fix this by sanitizing idx before using it to index data.states
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.
The current behaviour of cleaning the pointer is kept in the calling code,
but should be removed if not required in a later patch.
