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.
