x86: fsp: Reinit the FPU after FSP meminit
The APL FSP appears to leave the FPU in a bad state in that it has
registers in use. This causes an error when the next FPU operation is
performed.
Work around this by re-resetting the FPU after calling FSP-M. This allows
the freetype console to work correctly.
