f54b6bdf42 drm/amd/pm: add missing prototypes to amdgpu_dpm_internal
Include the header with the prototype to silence the following clang
warnings:

drivers/gpu/drm/amd/amdgpu/../pm/amdgpu_dpm_internal.c:29:6: warning: no
previous prototype for function 'amdgpu_dpm_get_active_displays'
[-Wmissing-prototypes]
void amdgpu_dpm_get_active_displays(struct amdgpu_device *adev)
     ^
drivers/gpu/drm/amd/amdgpu/../pm/amdgpu_dpm_internal.c:29:1: note: declare
'static' if the function is not intended to be used outside of this
translation unit
void amdgpu_dpm_get_active_displays(struct amdgpu_device *adev)
^
static
drivers/gpu/drm/amd/amdgpu/../pm/amdgpu_dpm_internal.c:76:5: warning: no
previous prototype for function 'amdgpu_dpm_get_vrefresh'
[-Wmissing-prototypes]
u32 amdgpu_dpm_get_vrefresh(struct amdgpu_device *adev)
    ^
drivers/gpu/drm/amd/amdgpu/../pm/amdgpu_dpm_internal.c:76:1: note: declare

u32 amdgpu_dpm_get_vrefresh(struct amdgpu_device *adev)
^
static
2 warnings generated.

Besides that, remove the duplicated prototype of the function
amdgpu_dpm_get_vblank_time in order to keep the consistency of the
headers.

685fae24d9 drm/amd/pm: correct the checks for fan attributes support
On functionality unsupported, -EOPNOTSUPP will be returned. And we rely
on that to determine the fan attributes support.

3712e7a494 drm/amd/pm: unified lock protections in amdgpu_dpm.c
As the only entry point, it's now safe and reasonable to
enforce the lock protections in amdgpu_dpm.c. And with
this, we can drop other internal used power locks.

837d542a09 drm/amd/pm: relocate the power related headers
Instead of centralizing all headers in the same folder. Separate them into
different folders and place them among those source files those who really
need them.
