Early printk has been removed already that's why this setting doesn't make
any sense. Also change printk level from pr_info to pr_err.
Fixes: 96f0e6fcc9ad ("microblaze: remove redundant early_printk support")

Add support for CCF for Microblaze.
Old binding:
system_timer: system-timer@41c00000 {
clock-frequency = <75000000>;
...
}
New binding:
system_timer: system-timer@41c00000 {
clocks = <&clk_bus>;
...
}
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>;
} ;
clk_cpu: cpu {
#clock-cells = <0>;
clock-frequency = <75000000>;
clock-output-names = "cpu";
compatible = "fixed-clock";
reg = <0>;
} ;
} ;

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.

We used cache_line as cache_line_lenght. For this reason
we did cache flushing 4 times longer than was necessary.
