MIPS: DSP: Fix DSP mask for registers.
The DSP bit mask for the RDDSP and WRDSP instructions was wrong.
[ralf@linux-mips.org: The mask field of the RDDSP and WRDSP instructions
is 10 bits long. DSP_MASK had all these fields which according to the
architecture specification may result in UNPREDICTABLE operation.]
