commit 94c82de43e01ef5747a95e4a590880de863fe423 upstream.

For Intel platform, it is required to configure PTP clock source prior PTP
initialization in MAC. So, need to move ptp_clk_freq_config execution from
stmmac_ptp_register() to stmmac_init_ptp().

Fixes: 76da35dc99af ("stmmac: intel: Add PSE and PCH PTP clock source selection")
