drm/amdgpu: Fix memcpy() in sienna_cichlid_append_powerplay_table function.
[ Upstream commit d50dc746ff72b9c48812dac3344fa87fbde940a3 ]
Fixes the following gcc with W=1:

the compiler complains about the size calculation in the memcpy() -
"sizeof(*smc_dpm_table) - sizeof(smc_dpm_table->table_header)" is much
larger than what fits into table_member.
Hence, reuse 'smu_memcpy_trailing' for nv1x
