There should be no svvptc in the riscv-ext-bitmask.def file since it has
not yet been added to the RISC-V C API Specification or the Linux
hwprobe. And there is no need for userspace software to know that this
extension exists. So remove it from the riscv-ext-bitmask.def file.

I think we'll likely never expose this to userspace, the mappings are
all hidden behind kernel interfaces so userspace shouldn't need to know.
I've pushed this patch to the trunk.
