package: u-boot: initial support for qoriq arch

This package adds initial u-boot support for qoriq target.

U-boot for qoriq devices must be compiled with 32-bit compiler and
linked with 32-bit linker. It's part of mpc 85xx target. But qoriq
target is 64-bit. As workaround, mpc85xx binary toolchain is downloaded
only for this u-boot.
