When breaking out the Gen4 gPTP support to its own module the dependency on the PTP_1588_CLOCK framework was left as optional and only stated for the driver using the module. This leads to issues when doing COMPILE_TEST of RENESAS_GEN4_PTP separately and PTP_1588_CLOCK is built as a module and the other as a built-in. Add an explicit depend on PTP_1588_CLOCK. While at it remove the optional support for PTP_1588_CLOCK from RENESAS_ETHER_SWITCH as the driver unconditionally calls the Gen4 gPTP module and thus also requires the PTP_1588_CLOCK framework.
