Building bcm2835_defconfig, which has CONFIG_CONFIG_VFPv3=n causes the following
build warning:
arch/arm/vfp/vfpmodule.c: In function 'vfp_init':
arch/arm/vfp/vfpmodule.c:725:6: warning: unused variable 'mvfr0' [-Wunused-variable]
u32 mvfr0;
^
As mvfr0 is only used inside a '#ifdef CONFIG_VFPv3' code block, protect its
definition accordingly to avoid the warning.
