* irq/irq_asm.S: Currently, all (new exception) BSPs explicitely enable
the FPU across the user ISR but DONT save/restore the FPU context.
Any use of the FPU fron the user handler (e.g., due to GCC
optimizations) result in corruption. The fix results in an exception
in such cases (user ISR must explicitely save/enable/restore FPU).
