net: phy: Kconfig: micrel_phy: fix dependency issue

Browse Source 
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
e5f3155267 ("ethernet: fix PTP_1588_CLOCK dependencies").
