FDT: use static phandles
The current implementation of fdt__alloc_phandle() suffers from being
implemented in a static inline function situated in a header file.
This will only create expected results within a single compilation
unit.
It seems a bit over the top to use a function to allocate phandles,
when at the end of the day a phandle is just a unique identifier.
To simplify things - especially with upcoming patches - we just
introduce an enum per architecture to hold all possible phandle sources
and use that instead of the dynamic allocation.
