drm/amdgpu/pm: Account for extra separator characters in sysfs interface
Currently, the the input to the pp_od_clk_voltage sysfs interface has
two adjacent separator characters, i.e. "\n\0", then we try to parse an
argument out of the empty string, whereas we really should just ignore
this case, and treat any number of adjacent separators as one separator
for arguments.
We do this here by simply skipping the argument parsing for all
empy-string arguments.
An example test case would be `echo 's 1 900' > pp_od_clk_voltage`
(note the two spaces after the 's'.
This also solves the issue where the written string ends with both a
newline, and a nul-terminator, '\n\0', as is the case for `echo 's 1
900' > pp_od_clk_voltage` since the recent rebase.

It will hopefully also provide fixes for other DCE's up to
DCE-11, assuming those will need similar fixes, but i could
not test that for HDMI due to lack of suitable hw, so viewer
discretion is advised.
dce110_stream_encoder_hdmi_set_stream_attribute() is used for
HDMI setup on all DCE's and is missing color_depth assignment.
dce110_program_pix_clk() is used for pixel clock setup on HDMI
for DCE 6-11, and is missing color_depth assignment.
Additionally some of the underlying Atombios specific encoder
and pixelclock setup functions are missing code which is in
the classic amdgpu kms modesetting path and the in the radeon
kms driver for DCE6/DCE8.
encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
and radeon kms classic drivers. Added here, but untested due to
lack of suitable test hw.
encoder_control_digx_v4() - Added missing setup code.
Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
output at 10 bpc and 12 bpc.
Note that encoder_control_digx_v5() has proper setup code in place
and is used, e.g., by DCE-11.2, but this code wasn't used for deep
color setup due to the missing cntl.color_depth setup in the calling
function for HDMI.

[WHY]
Previously as MPO + ODM Combine was not supported, finding secondary pipes

drm: Upcast struct drm_device.dev to struct pci_device; replace pdev
We have DRM drivers based on USB, SPI and platform devices. All of them
are fine with storing their device reference in struct drm_device.dev.
PCI devices should be no exception. Therefore struct drm_device.pdev is
deprecated.
Instead upcast from struct drm_device.dev with to_pci_dev(). PCI-specific
code can use dev_is_pci() to test for a PCI device. This patch changes
the DRM core code and documentation accordingly.
