In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Drivers that can optionally use the PTP_1588_CLOCK framework
should depend on this symbol to prevent them from being built
into vmlinux while the PTP support itself is in a loadable
module.
If PTP support is disabled, this dependency will still be
met, and drivers refer to dummy helpers.
