[PATCH v2 1/2] drm/amdgpu/jpeg: deduplicate jpeg_v3_0 process_interrupt

[Tiago Dourado]

The jpeg_v3_0_process_interrupt function is identical to
jpeg_v2_0_process_interrupt. Remove the duplicate implementation
in jpeg_v3_0 and assign the jpeg_v2_0 version directly to the irq_funcs struct.
Export jpeg_v2_0_process_interrupt through jpeg_v2_0.h to allow
cross-version reuse.

v2:
- Assigned function directly to irq_funcs instead of using a macro.
