Herve Codina b38736ac01
powerpc/8xx: Use a larger CPM1 command check mask 
The CPM1 command mask is defined for use with the standard
CPM1 command register as described in the user's manual:
  0  |1        3|4    7|8   11|12      14| 15|
  RST|    -     |OPCODE|CH_NUM|     -    |FLG|

In the QMC extension the CPM1 command register is redefined
(QMC supplement user's manuel) with the following mapping:
  0  |1        3|4    7|8           13|14| 15|
  RST|QMC OPCODE|  1110|CHANNEL_NUMBER| -|FLG|

Extend the check command mask in order to support both the
standard CH_NUM field and the QMC extension CHANNEL_NUMBER
field.
