[arm, patch] generic coprocessor register names in MaverickCrunch instructions

[Vladimir Ivanov]

Hello,

This small patch adds GAS support for using generic coprocessor register 
names (c0..c15) in MaverickCrunch instructions.

Currently, it is something like:
 	cfaddd mvd2, mvd0, mvd1

Now it is also possible to use:
 	cfaddd c2, c0, c1

This is due to customers request and EP93xx User Manual.

  * gas/config/tc-arm.c (mav_reg_required_here): Allow REG_TYPE_CN as
  alternative when REG_TYPE_MVF, REG_TYPE_MVD, REG_TYPE_MVFX or
  REG_TYPE_MVDX is expected.
