Commit 6deb535950 ("net: remove unused ATM protocols and legacy
ATM device drivers") removed the remaining in-tree users of
atm_alloc_charge(), atm_pcr_goal(), sonet_copy_stats() and
sonet_subtract_stats().
Remove these unused exported helpers and their declarations. The
removal of the SONET statistics helpers also leaves
include/linux/sonet.h without users, so remove the internal header and
its MAINTAINERS entry.
