[POWERPC] QE: 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. Fully define 'struct rsp' in immap_qe.h to
include the actual RISC Special Registers. Added description of a new
QE firmware node to booting-without-of.txt.

+ viii) Uploaded QE firmware
+
+ If a new firwmare has been uploaded to the QE (usually by the
+ boot loader), then a 'firmware' child node should be added to the QE
+ node. This node provides information on the uploaded firmware that
+ device drivers may need.
+
+ Required properties:
+ - id: The string name of the firmware. This is taken from the 'id'
+ member of the qe_firmware structure of the uploaded firmware.
+ Device drivers can search this string to determine if the
+ firmware they want is already present.
+ - extended-modes: The Extended Modes bitfield, taken from the
+ firmware binary. It is a 64-bit number represented
+ as an array of two 32-bit numbers.
+ - virtual-traps: The virtual traps, taken from the firmware binary.
+ It is an array of 8 32-bit numbers.
+
+ Example:
+
+ firmware {
+ id = "Soft-UART";
+ extended-modes = <0 0>;
+ virtual-traps = <0 0 0 0 0 0 0 0>;
+ }
