ravb: factor out register bit twiddling code
The driver has often repeated pattern of reading a register, AND'ing and/or
OR'ing some bits and writing the value back. Factor the pattern out into
ravb_modify() -- this saves 260 bytes of code with ARM gcc 4.7.3.
While at it, update Cogent Embedded's copyrights.
