 bsps/sparc: Add leon3 BSP variants

 Rename NGMP to GR740 and add configs for UT699, UT700, and GR712RC

 The UT699 requires -mcpu=leon as it does not support the CAS instruction
 provided by -mcpu=leon3. It also requires -mfix-ut699 for errata fixes.

 UT700 and GR712RC requires the -mfix-ut700 and -mfix-gr712rc flags that
 have been recently added to GCC's master and 7-branch.

 Remove -msoft-float from the leon3 config to make the more common case
 of using the FPU the default.

 Update #3057.
