[arm] Add default FPU for Marvell-pj4

According to GAS, the Marvell PJ4 CPU has a VFPv3-D16 floating point
unit, but GCC's CPU configuration tables omits this meaning that
-mfpu=auto will not correctly select the FPU.  This patch fixes this
by adding the +fp option to the architecture specification for this
device.

	* config/arm/arm-cpus.in (marvel-pj4): Add +fp to the architecture.
