Subject: [PATCH net] net: dsa: sja1105: Add dependency for NET_DSA_SJA1105_TAS

If CONFIG_NET_DSA_SJA1105_TAS=y and CONFIG_NET_SCH_TAPRIO=n,
below error can be found:
drivers/net/dsa/sja1105/sja1105_tas.o: In function `sja1105_setup_tc_taprio':
sja1105_tas.c:(.text+0x318): undefined reference to `taprio_offload_free'
sja1105_tas.c:(.text+0x590): undefined reference to `taprio_offload_get'
drivers/net/dsa/sja1105/sja1105_tas.o: In function `sja1105_tas_teardown':
sja1105_tas.c:(.text+0x610): undefined reference to `taprio_offload_free'
make: *** [vmlinux] Error 1

sja1105_tas needs tc-taprio, so this patch add the dependency for it.
