[PATCH 1/3] arm64: Don't number registers in cpu-feature-registers.rst

cpu-feature-regsters.rst documents the set of userspace visible ID
registers. At present the section for each register is numbered, this has
lead to the registers being documented in a haphazard order as new ones
have been added to the end of the list to avoid renumbering. Remove the
numbers so we can avoid this problem in future.
