Turn previously global functions into static functions to avoid
-Wmissing-prototype warnings, such as:

drivers/gpu/drm/amd/amdgpu/../display/dc/irq/dcn30/irq_service_dcn30.c:50:20:
warning: no previous prototype for function 'to_dal_irq_source_dcn30'
[-Wmissing-prototypes]
enum dc_irq_source to_dal_irq_source_dcn30(
                   ^
drivers/gpu/drm/amd/amdgpu/../display/dc/irq/dcn30/irq_service_dcn30.c:50:1:
note: declare 'static' if the function is not intended to be used outside
of this translation unit
enum dc_irq_source to_dal_irq_source_dcn30(
