[PATCH V3] drm/amd/pm: Refactor SMU 13.0.6 SDMA reset firmware version checks

[Jesse.zhang@amd.com]

From: "Jesse.zhang at amd.com" <Jesse.zhang at amd.com>

This patch refactors the firmware version checks in `smu_v13_0_6_reset_sdma`
to support multiple SMU programs with different firmware version thresholds.

V2: return -EOPNOTSUPP for unspported pmfw
V3: except IP_VERSION(13, 0, 12) which is not supported.
