drm/xe: Fix logical mask for parallel engines

Matthew Brost requested to merge (removed):fix_parallel_logical_mask into xe

The logical mask for parallel engines should be a single bit for each placement.

e.g. If we want to place a 2 wide submission VCS0-1, the logical mask should be 0x1.

e.g. If we want to place a 2 wide submission on CCS0-1 or CCS2-3, the logical mask should be 0x5.

The logic to setup the logical mask was wrong, fix it.
