The Gen4 gPTP support will be shared between the existing Renesas
Ethernet Switch driver and the upcoming Renesas Ethernet-TSN driver. In
preparation for this break out the gPTP support to its own module.

* Changes since v2
- Drop the unneeded 'depends on' line from Kconfig symbol
  RENESAS_GEN4_PTP.

* Changes since v1
- s/Gen3/Gen4/ in commit message.
- Add missing MODULE_AUTHOR() and MODULE_DESCRIPTION() definitions.
- Make Kconfig tristate depend on COMPILE_TEST. All drivers that make
  use of the shared code auto selects this anyhow.
