powerpc/p1010rdb: nandboot: compare SVR properly 

We were not comparing the SVRs properly previously. This comparison
will properly shift the SVR and mask off the E bit

This fixes the boot output to show the correct DDR bus width:

512 MiB (DDR3, 16-bit, CL=5, ECC off)

instead of

512 MiB (DDR3, 32-bit, CL=5, ECC off)
