Microblaze without MMU can use stack protection in bootloader
and kernel should clear this setting ASAP.

Do not keep NOTES section align in proper location.
'readelf' shows that 'NOTE' is placed in wrong location
which is out of virtual and physical load addresses.

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";
