g infrastructure.

- User impact
  - Fixes missing RAS enablement: poison error reporting/handling and
    ACA binding (drivers/gpu/drm/amd/amdgpu/jpeg_v5_0_1.c:1068) now work
    for JPEG v5.0.1.
  - Prevents potential WARNs from unbalanced IRQ enable/disable paths on
    RAS-capable hardware.

- Stable backport suitability
  - Fixes a real functional gap in error handling on supported hardware.
  - Minimal and self-contained, consistent with stable rules.
  - No new features or ABI changes; guarded by capability checks.

Given the above, this is a straightforward, low-risk bugfix that aligns
v5.0.1 with other JPEG IP versions and should be backported.
