accel/habanalabs: fix address decode RAZWI handling

Browse source

PSOC RAZWI handling code did not took into account single router that
supports several initiators with different XY coordinates. Also, it
ignored XY_HI coordinate. This caused 2 problems:
1. RAZWI handle ignored some initiators.
2. When getting PSOC RAZWI from some routers, there was a lot of
   possible engines which could have caused the RAZWI.

Fixed the above issue by handling PSOC RAZWI with both low and high
XY coordinates. This way driver supports all initiators and in
the worst case there are not more than 2 possible engines for RAZWI.
