slimbus: Use appropriate Pipe Number Offset Mask 



Pipe Number Offset field for BAM Pipes to be used by Slimbus is configured
in Slimbus NGD Status register from bit field 2 to bit field 9. Currently
the mask is taking only the bit fields 2 to 7.

Update the Pipe Number Offset Mask to include the bit fields 2 to 9.
