lm4f: Enable FPU using the vector_chipset hook

Browse Source 
Newlib and arm-non-eabi-gcc likes to use the FPU by default on
Cortex-M4F chips. AS a result, do the right thing and enable the FPU
by default.

This fixes issues where code is generated which uses the FPU and
causes the CPU to hard-fault. This change removes the responsibility
of FPU initialization from the application code.

This makes the lm4f consistent with other M4+ devices that enable the
FPU in core library startup code.
