of: make default address and size cells sizes private

Browse source 
Only some old OpenFirmware implementations rely on default sizes. Any
FDT and modern implementation should have explicit properties. Make the
OF_ROOT_NODE_*_CELLS_DEFAULT defines private so we don't get any outside
users.

This also gets us one step closer to removing the asm/prom.h dependency on
Sparc.
