85xx: Report which "bank" of NOR flash we are booting from on FSL boards
The p2020DS, MPC8536DS, MPC8572DS, MPC8544DS boards are capable of swizzling the upper address bits of the NOR flash we boot out of which creates the concept of "virtual" banks. This is useful in that we can flash a test of image of u-boot and reset to one of the virtual banks while still maintaining a working image in "bank 0". The PIXIS FPGA exposes registers on LBC which we can use to determine which "bank" we are booting out of (as well as setting which bank to boot out of).
