Scott Wood e57eeae4e6 powerpc/fsl-booke64: Set vmemmap_psize to 4K 
The only way Freescale booke chips support mappings larger than 4K
is via TLB1.  The only way we support (direct) TLB1 entries is via
hugetlb, which is not what map_kernel_page() does when given a large
page size.

Without this, a kernel with CONFIG_SPARSEMEM_VMEMMAP enabled crashes on
boot with messages such as:

PID hash table entries: 4096 (order: 3, 32768 bytes)
Sorting __ex_table...
