ARM: MMU: fix wrong dma_flush_range in arm_create_pte()
Since 7ba0f2d299 arm_create_pte() flushes the page table entries itself
and it's no longer done in arch_remap_range(). Unfortunately it does
not flush the modified 1st level page table entry, but instead the base
of the page table. Fix it up.
Fixes: 7ba0f2d299 ARM: mmu: fix cache flushing when replacing a section with a PTE
