[PATCH v1 12/20] powerpc/32s: Inline flush_tlb_range() and flush_tlb_kernel_range()

[Christophe Leroy <christophe.leroy@csgroup.eu>]

flush_tlb_range() and flush_tlb_kernel_range() are trivial calls to
flush_range().

Make flush_range() global and inline flush_tlb_range()
and flush_tlb_kernel_range().
