checkpatch: port fix from kernel "## is not a valid modifier"

checkpatch currently loops on fpu/softfloat.c
Turns out this is fixed in the Linux version of checkpatch.

So this is a port of Andy Whitcrofts fix from Linux,
Original commit was commit 89a883530fe7 ("checkpatch: ## is not a
valid modifier")

As suggested by Peter Maydell for the QEMU version we drop the last "|"
as there seems to be no need for that. (FWIW, the kernel discusion about
that dried out:
