microblaze: Add support for CCF

Add support for CCF for Microblaze.

New binding:

Both should be supported for a while

Microblaze clock binding:
clocks {
#address-cells = <1>;
#size-cells = <0>;
clk_bus: bus {
#clock-cells = <0>;
clock-frequency = <75000000>;
clock-output-names = "bus";
compatible = "fixed-clock";
reg = <1>;

clock-output-names = "cpu";
compatible = "fixed-clock";
reg = <0>;

microblaze: Unprivileged stream instruction awareness

Add cpuinfo support for the new MicroBlaze option permitting userspace
(unprivileged) access to the streaming instructions (FSL / AXI-stream).

microblaze: Unprivileged stream instruction awareness

Add cpuinfo support for the new MicroBlaze option permitting userspace
(unprivileged) access to the streaming instructions (FSL / AXI-stream).

Emit a noisy warning at bootup if this is enabled, because bad user code
can potentially lockup the CPU.
