PATCH 1/1 ptp: Fix documentation to match code.
Ever since commit 3a06c7ac24f9 ("posix-clocks: Remove interval timer facility and mmap/fasync callbacks") the possibility of PHC based posix timers has been removed. In addition it will probably never make sense to implement this functionality.
This patch removes the misleading text which seems to suggest that posix timers for PHC devices will ever be a thing.
