mvebu: cortexa9: correct cpu subtype
Armada 370 processors have only 16 double-precision registers. The
change introduced by 8dcc1087602e ("toolchain: ARM: Fix toolchain
compilation for gcc 8.x") switched accidentally the toolchain for mvebu
cortexa9 subtarget to cpu type with 32 double-precision registers. This
stems from gcc defaults which assume "vfpv3-d32" if only "vfpv3" as mfpu
is specified. That change resulted in unusable image, in which kernel
will kill userspace as soon as it causing "Illegal instruction".
