Srinivasan Shanmugam 85b495bbbe drm/amd/amdgpu/vcn: Fix kdoc entries for VCN clock/power gating functions
This commit corrects the descriptors for the
vcn_v4_0/v4_0_3/v4_0_5/v5_0_0 _set_clockgating_state and
vcn_v4_0/v4_0_3/v4_0_5/v5_0_0 _set_powergating_state functions in the
amdgpu driver.

The parameter descriptors in the comments were mismatched with the
actual function parameters. The non-existent 'handle' parameter has been
replaced with the correct 'ip_block' parameter in the comments to
accurately reflect the function signatures and to resolving the below
with gcc W=1:

Avoid returning an uninitialized value if we never enter the loop.
This case should never be hit in practice, but returning 0 doesn't
hurt.

The same fix is applied to the 4 places using the same pattern.

v2: - fixed typos in commit message (Alex)
    - use "return 0;" before the done label instead of initializing
      r to 0
