[Intel-xe] [PATCH i-g-t 13/14] lib/intel_blt: Support xe2 in xy-fast-copy command

[Lucas De Marchi]

Xe2 xy-fast-copy command is slightly different, with dw01 and dw07
having a few differences: 1) different bitrange for mocs (it was
previously absent in dw07); 2) no dst_memory, src_memory;
3) hardcoded dst_type_y and src_type_y to 1.
