Subject: sfc: siena: Fix Kconfig dependencies
Patch-mainline: v5.19-rc1
Git-commit: f9a210c72d70c9a59cf989fb23fb01ff10d18136
References: jsc#PED-1565

If CONFIG_PTP_1588_CLOCK=m and CONFIG_SFC_SIENA=y, the siena driver will fail to link:

drivers/net/ethernet/sfc/siena/ptp.o: In function `efx_ptp_remove_channel':
ptp.c:(.text+0xa28): undefined reference to `ptp_clock_unregister'
drivers/net/ethernet/sfc/siena/ptp.o: In function `efx_ptp_probe_channel':
ptp.c:(.text+0x13a0): undefined reference to `ptp_clock_register'
ptp.c:(.text+0x1470): undefined reference to `ptp_clock_unregister'
drivers/net/ethernet/sfc/siena/ptp.o: In function `efx_ptp_pps_worker':
ptp.c:(.text+0x1d29): undefined reference to `ptp_clock_event'
drivers/net/ethernet/sfc/siena/ptp.o: In function `efx_siena_ptp_get_ts_info':
ptp.c:(.text+0x301b): undefined reference to `ptp_clock_index'

To fix this build error, make SFC_SIENA depends on PTP_1588_CLOCK.
