drm/amd/pm: avoid unaligned access warnings

When building on OpenBSD/arm64 with clang 15, unaligned access
warnings are seen when a union is embedded inside a packed struct.

drm/amd/pm/powerplay/hwmgr/vega20_pptable.h:136:17: error: field
smcPPTable within 'struct _ATOM_VEGA20_POWERPLAYTABLE' is less aligned
than 'PPTable_t' and is usually due to
'struct _ATOM_VEGA20_POWERPLAYTABLE' being packed, which can lead to
unaligned accesses [-Werror,-Wunaligned-access]
PPTable_t smcPPTable;
^

Make PPTable_t packed to avoid this.

drm/amdgpu: Fix unique_id references for Sienna Cichlid

Since unique_id is only supported in PMFW 0x3A5300 and higher, we will
only be able to use it inside Smu_Metrics_V3_t, which requires PMFW
0x3A4900 and higher. Remove the unique_id/serial_number references from
the v1 and v2 tables to avoid any confusion, and return 0 if metrics_v1
or metrics_v2 are used to try to get the unique_id/serial_number.

drm/amd/pm: relocate the power related headers

Instead of centralizing all headers in the same folder. Separate them into
different folders and place them among those source files those who really
need them.
