Set the cacheline size before calling powerpc_init()

Browse Source 
powerpc_init() initializes the mmu.  Since this may clear pages via
pmap_zero_page(), set the cacheline size before calling into it, so
pmap_zero_page() has the right cacheline size.  This isn't completely
necessary now, but will be when 64-bit book-e is completed.
