[RFC PATCH v2 2/5] ARM: mm: rename jump labels in v7_flush_dcache_all function

[Lorenzo Pieralisi]

This patch renames jump labels in v7_flush_dcache_all in order to define
a specific flush cache levels entry point.

TODO: factor out the level flushing loop if considered worthwhile and
      define the input registers requirements.
