[PATCH v2 2/5] staging: vt6655: Rename function MACvReceive0 and add parameter

[Philipp Hortmann <philipp.g.hortmann@gmail.com>]

Rename MACvReceive0 function to vt6655_mac_dma_ctl to avoid CamelCase
which is not accepted by checkpatch.pl and to clean up namespace. Add
one parameter to avoid multiple repetitions of the same function.

V1 -> V2: Combind patch "Add parameter to function vt..." with this one
          Changed order of renaming function and conversion to function
          Improved patch description
