drm/amd/display: always-true lower-bound assert

Browse Source 
[Why]
A recent type change made the lower-bound part of the OTG instance
assert redundant, which can trigger static-analysis noise and distract
from actionable diagnostics.

[How]
Kept the meaningful upper-bound range validation required for safe
narrowing to uint8_t. Removed the redundant non-negative portion of the
assert so the check matches current type semantics. Revalidated with the
latest debug build log: no warnings and no build-failure markers.
