csky/dma: Fixup cache_op failed when cross memory ZONEs
If the paddr and size are cross between NORMAL_ZONE and HIGHMEM_ZONE
memory range, cache_op will panic in do_page_fault with bad_area.
Optimize the code to support the range which cross memory ZONEs.
Changes for V2:
- Revert back to postcore_initcall
