powerpc/prom_init: Move custom isspace() to its own namespace
If by some reason any of the headers will include ctype.h
we will have a name collision. Avoid this by moving isspace()
to the dedicate namespace.
First appearance of the code is in the commit cf68787b68a2
("powerpc/prom_init: Evaluate mem kernel parameter for early allocation").
