drm/amd: Drop debugfs access to the DPCD

There is already access to the DPCD from userspace through
`CONFIG_DRM_DP_AUX_CHARDEV`, so it's unnecessary to reinvent the wheel
with a set of extra debugfs nodes specific to amdgpu.

The character device interface behaves more like you would expect in that
you can seek/read/write all from the same file.

drm/amd/pm: reverse mclk and fclk clocks levels for renoir

This patch reverses the DPM clocks levels output of pp_dpm_mclk
and pp_dpm_fclk for renoir.

On dGPUs and older APUs we expose the levels from lowest clocks

given the reversed orders by PMFW. Like the memory DPM clocks
that are exposed by pp_dpm_mclk.

It's not intuitive that they are reversed on these APUs. All tools
and software that talks to the driver then has to know different ways
to interpret the data depending on the asic.

This patch reverses the DPM clocks levels output of pp_dpm_mclk.

On dGPUs and older APUs we expose the levels from lowest clocks
to highest clocks. But for some APUs, the clocks levels that from
the DFPstateTable are given the reversed orders by PMFW. Like the

It's not intuitive that they are reversed on these APUs. All tools
and software that talks to the driver then has to know different ways
to interpret the data depending on the asic.

So we need to reverse them to expose the clocks levels from the
driver consistently.

drm/amd/display: lower dp link training message level

[Why] some test apps report dp link training waring even dp
training pass. there are 4 tries of lt within
perform_link_training_with_retries. if lt pass within 4 tries,
it will NOT be reated as lt failure. for each try of lt, if lt
fails, current driver implementation prints message at warning
level. this let people think dp lt does not work properly.

[How] for 1st, 2nd and 3rd try of lt, print message at debug
level. for the 4th try of lt, print message at warning level.

drm/amd/display: Fix warning in disabling vblank irq

[Why]
During gpu-reset, we toggle vblank irq by calling dc_interrupt_set()
instead of amdgpu_irq_get/put() because we don't want to change the irq
source's refcount. However, we see the warning when vblank irq is enabled
by dc_interrupt_set() during gpu-reset but disabled by amdgpu_irq_put()
after gpu-reset.

[How]
Only in dm_gpureset_toggle_interrupts() we toggle vblank interrupts by
calling dc_interrupt_set(). Apart from this we call dm_set_vblank()
which uses amdgpu_irq_get/put() to operate vblank irq.

drm/radeon: reintroduce radeon_dp_work_func content

Put back the radeon_dp_work_func logic.  It seems that
handling DP RX interrupts is necessary to make some
panels work.  This was removed with the MST support,
but it regresses some systems so add it back.  While
