arch-microblaze.inc: Add 'frequency-optimized' tune
With MicroBlaze v10.0 an additional AREA_OPTIMIZED value of 2 was added
named Frequency. This optimization adds additional pipeline stages, and
code can be optimized differently to achieve better tuned performance
for these targets.
The '-mxl-frequency' flag has been added to GCC (not in mainline) to
enable specific tune optimizations for CPUs configured this way.
Whilst this tune does not change any ABI the addition of the 'fo'
package arch flag is added to allow for building both target optimized
and un-optimized without mixing packages.
