arm: Tidy up flush_xen_dcache().
- Use a compile-time-constant check for whether we can safely flush
just one cacheline. This reduces the common case from 28
instructions to three.
- Pass an object to the macro, not a pointer, so we can detect
attempts to flush arrays.
- Decode CCSIDR correctly to get cacheline size.
- Remove some redundant DSBs at the call sites.
