[PATCH-for-8.0] linux-user/mips: Use P5600 as default CPU to run NaN2008 ELF binaries |

Per the release 6.06 revision history:
5.03 August 21, 2013
• ABS2008 and NAN2008 fields of Table 5.7 “FCSR RegisterField
Descriptions” were optional in release 3 and could be R/W,
but as of release 5 are required, read-only, and preset by
hardware.
The P5600 core implements the release 5, and has the ABS2008
and NAN2008 bits set in CP1_fcr31. Therefore it is able to run
ELF binaries compiled with EF_MIPS_NAN2008, such the CIP United
Debian NaN2008 distribution:
http://repo.oss.cipunited.com/mipsel-nan2008/README.txt
In order to run such compiled binaries, select by default the
P5600 core when the ELF 'MIPS_NAN2008' flag is set.
