net: fec: Use a spinlock to guard `fep->ptp_clk_on`
Mutexes cannot be taken in a non-preemptible context,
causing a panic in `fec_ptp_save_state()`. Replacing
`ptp_clk_mutex` by `tmreg_lock` fixes this.
Fixes: 6a4d7234ae9a ("net: fec: ptp: avoid register access when ipg clock is disabled")
Fixes: f79959220fa5 ("fec: Restart PPS after link state change")
