npu2: Use read-modify-write in npu2_assign_gmb()
We currently set each half of the GPU memory BAR by OR'ing our half
into what is already there. This allows a possible conflict if Hostboot
or other system boot software has already written to the BAR.
Set each half of the BAR value directly instead of using OR.
