drm/amd/display: Fix dmub_cmd header alignment

Browse source

[ Upstream commit 327aba7f55 ]

[why & how]
Header misalignment in struct dmub_cmd_replay_copy_settings_data and
struct dmub_alpm_auxless_data causes incorrect data read between driver
and dmub.
Fix the misalignment and ensure that everything is aligned to 4-byte
boundaries.
