1. Support for Fixed Virtual Platforms(FVP) Base RevC model to enable
development of software around the new features available
2. Addition of dynamic-power-coefficient information for CPUs on Juno
3. Miscellaneous changes like re-ordering device nodes, using existing
macros for GIC flags in interrupt-maps and using list instead of
tuple(which is wrong but works as number of interrupt cells is 1)
for mmci interrupts
