drm/xe/irq: Drop commented-out code for non-existent media engines

Although the hardware team has set aside some register bits for extra
media engines, no platform supported by the Xe driver today has VCS4-7
or VECS2-3.  Drop the corresponding code (which was already commented
out); we can bring it back easily enough if such engines show up on a
future platform.
