drm/amd/display: Clean up style problems in amdgpu_dm_irq.c

Fix the following warnings reported by checkpatch:

WARNING: Block comments use a trailing */ on a separate line
WARNING: Comparisons should place the constant on the right side of the test
WARNING: space prohibited between function name and open parenthesis '('
WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
