net: stmmac: configure PTP clock source prior to PTP initialization

Browse Source 
commit 94c82de43e 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: 76da35dc99 ("stmmac: intel: Add PSE and PCH PTP clock source selection")
