drm/amdgpu:mark aqua_vanjaram_reg_init.c function as static

A few newly added global functions have no prototype, which causes warnings:

drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c:169:5: error: no previous prototype for 'aqua_vanjaram_select_scheds' [-Werror=missing-prototypes]
drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c:310:5: error: no previous prototype for '__aqua_vanjaram_get_xcc_per_xcp' [-Werror=missing-prototypes]
drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c:337:5: error: no previous prototype for '__aqua_vanjaram_get_xcp_ip_info' [-Werror=missing-prototypes]
drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c:593:5: error: no previous prototype for 'aqua_vanjaram_get_xcp_ip_details' [-Werror=missing-prototypes]

There are no callers from other files, so just mark them as 'static'.
