85xx: add ability to upload QE firmware
Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Add command-line command "qe fw" to take a firmware blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the 'firmware' device tree node if U-Boot has uploaded a firmware. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Signed-off-by: Timur Tabi <timur@freescale.com>
