stmmac: ptp: fix the reference clock
The PTP reference clock, used for setting the addend in the Timestamp Addend Register, was erroneously hard-coded (as reported in the databook just as example). The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a reference clock (clk_ptp_ref_i) that can be passed from the platform. If not passed, the main driver clock will be used as default; note that this can be fine on some platforms. Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms, as side effect, the ptp clock can move faster/slower than the system clock.
