Remove the definition of QT_NO_FPU based on the processor or WS

Browse Source 
The definition is just wrong these days. Modern ARMv7 and MIPS have
FPUs. Maybe AVR32, SH or SH4A don't, but then QT_NO_FPU should be
defined in the qplatformdefs.h for those platforms.

More importantly, since QPA is the only supported architecture for Qt
5, we definitely don't want to say that no platforms have no FPU.

Still let qreal be defined to float on ARM, though: on Cortex-A8,
which is the current norm these days, float performance is better than
double performance.
