Building without CONFIG_PTP_1588_CLOCK results in multiple failures,
this was obviously not well tested:
drivers/net/ethernet/microchip/lan743x_ptp.c: In function 'lan743x_ptp_isr':
drivers/net/ethernet/microchip/lan743x_ptp.c:781:28: error: 'struct lan743x_ptp' has no member named 'ptp_clock'; did you mean 'tx_ts_lock'?
ptp_schedule_worker(ptp->ptp_clock, 0);

Those #ifdef checks are hard to get right, replace them all with
IS_ENABLED() checks that leave the same code visible to the compiler
but let it optimize out the unused bits based on the configuration.
