Stephen Rothwell reports that commit 3f4c9f8f0a20 ("ARM: 8197/1:
vfp: Fix VFPv3 hwcap detection on CPUID based cpus") introduced an
unused variable 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;

Silence this warning by using IS_ENABLED instead of ifdefs.

Looks good (though I haven't tested it).  One small nit below:

+		if (IS_ENABLED(CONFIG_VFPv3)) {
+			mvfr0 = fmrx(MVFR0);

Now that you have a block here, you could move the declaration of mvfr0
into this block, right?
