drm/amd/powerplay: fix variable type errors in smu_v11_0_setup_pptable
fix size type errors, from uint32_t to uint16_t.
it will cause only initializes the highest 16 bits in
smu_get_atom_data_table function.
bug report:
This fixes the following static checker warning.
drivers/gpu/drm/amd/amdgpu/../powerplay/smu_v11_0.c:390 smu_v11_0_setup_pptable()
warn: passing casted pointer '&size' to 'smu_get_atom_data_table()' 32 vs 16.
