stmmac: fix and review the ptp registration.
The commit commit 7086605a6ab5 ("stmmac: fix error check when init ptp")
breaks the procedure added by the
commit efee95f42b5d ("ptp_clock: future-proofing drivers against PTP
subsystem becoming optional")
So this patch tries to re-import the logic added by the latest
commit above: it makes sense to have the stmmac_ptp_register
as void function and, inside the main, the stmmac_init_ptp can fails
in case of the capability cannot be supported by the HW.
