[PATCH 04/10] drm/amdgpu: fix function scopes

[Isabella Basso <isabbasso@riseup.net>]

This turns previously global functions into static, thus removing
compile-time warnings such as:

 warning: no previous prototype for 'release_psp_cmd_buf' [-Wmissing-prototypes]
 521 | void release_psp_cmd_buf(struct psp_context *psp)
     |      ^~~~~~~~~~~~~~~~~~~
 ...
 warning: no previous prototype for 'amdgpu_vkms_output_init' [-Wmissing-prototypes]
 399 | int amdgpu_vkms_output_init(struct drm_device *dev,
     |     ^~~~~~~~~~~~~~~~~~~~~~~
