configs/qemu_ppc64*: remove binutils version from defconfigs
Buildroot 2022.05 use binutils 2.37 by default, but the binutils
version was downgraded to the previous binutils version in qemu_ppc64*
defconfigs due to a bug in binutils 2.37 [1].
Later when binutils 2.36 has been removed the binutils version has
been updated to 2.38 (even though it was already the default version
selected by Buildroot at that time) [2].
Since then, several binutils release has been added and the binutils
version 2.38 has been removed recently [3].
Since the initial bug is gone with the removal of binutils 2.37,
we can safely remove the binutils version from qemu_ppc64 defconfigs.
