The default unit in powerplay is 10kHz
To convert from 10kHz to kHz, multiply by 10

This will clean up powerplay code, as we are no longer
multiplying the clocks by 1000 in DM and then dividing them
by 1000 in powerplay

Watermarks were being multiplied by 1000 in amdgpu_dm
and divided by 1000 in powerplay. Change watermarks
to units of MHz to stop doing that.

We were multiplying clock requests by 1000 in amdgpu_dm
and then dividing them by 1000 in powerplay.
Also, the vega12 code was dividing by 10 when it should have been
multiplying (to convert units of 10kHz to units of kHz).

- the initial eram and the
interrupt vectors. These are treated as seperate pieces of
firmware and loaded by PSP
The loading occurs in the sw_init hook of DM
If the firmware is not found, the sw_init hook returns without error.
DMCU is not a requirement for DM to run.

A few register addresses were declared in
amd/display/dc/dce*/dce*_resource.c.
They have been consolidated with the appropriate
master list of registers in
amd/include/asic_reg/dce/...
This will make them accessible to external tools that
need direct asic register access
