net: phy: Kconfig: micrel_phy: fix dependency issue
When building driver CONFIG_MICREL_PHY the follow error shows up: aarch64-linux-gnu-ld: drivers/net/phy/micrel.o: in function `lan8814_ts_info': micrel.c:(.text+0x1764): undefined reference to `ptp_clock_index' micrel.c:(.text+0x1764): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ptp_clock_index' aarch64-linux-gnu-ld: drivers/net/phy/micrel.o: in function `lan8814_probe': micrel.c:(.text+0x4720): undefined reference to `ptp_clock_register' micrel.c:(.text+0x4720): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ptp_clock_register' Rework Kconfig for MICREL_PHY to depend on 'PTP_1588_CLOCK_OPTIONAL'. Arnd describes in a good way why its needed to add this depends in patch e5f31552 ("ethernet: fix PTP_1588_CLOCK dependencies").
