net: dsa: sja1105: Build PTP support in main DSA driver

Browse Source 
As Arnd Bergmann pointed out in commit 78fe8a28fb ("net: dsa: sja1105:
fix ptp link error"), there is no point in having PTP support as a
separate loadable kernel module.

So remove the exported symbols and make sja1105.ko contain PTP support
or not based on CONFIG_NET_DSA_SJA1105_PTP.
