powerpc: drop ranges for definition of ARCH_FORCE_MAX_ORDER

PowerPC defines ranges for ARCH_FORCE_MAX_ORDER some of which are insanely
allowing MAX_ORDER up to 63, which implies maximal contiguous allocation
size of 2^63 pages.

Drop bogus definitions of ranges for ARCH_FORCE_MAX_ORDER and leave it a
simple integer with sensible defaults.

Users that *really* need to change the value of ARCH_FORCE_MAX_ORDER will
be able to do so but they won't be mislead by the bogus ranges.
