The enetc driver uses ifdefs when checking whether
CONFIG_FSL_ENETC_PTP_CLOCK is enabled in a number of places. This works
if the driver is built-in but fails if the driver is available as a
kernel module. Replace the instances of ifdef with use of the IS_ENABLED
macro, that will evaluate as true when this feature is built as a kernel
module and follows the kernel's coding style.

Changes since v1:
  - Switched from preprocessor conditionals to normal C conditionals.

Changes since v2:
  - Reworked enetc_ethtool.c changes to fit around changes merged in
    net-next.

Changes since v3:
  - Correction of SOB ordering.
  - Removal of unneeded `__maybe_unused` tags.
