Subject: [PATCH net v2] net: dsa: ocelot: add dependency for NET_DSA_MSCC_FELIX

If CONFIG_NET_DSA_MSCC_FELIX=y, and CONFIG_NET_VENDOR_MICROSEMI=n,
below errors can be found:
drivers/net/dsa/ocelot/felix.o: In function `felix_vlan_del':
felix.c:(.text+0x26e): undefined reference to `ocelot_vlan_del'
drivers/net/dsa/ocelot/felix.o: In function `felix_vlan_add':
felix.c:(.text+0x352): undefined reference to `ocelot_vlan_add'

and warning as below:
WARNING: unmet direct dependencies detected for MSCC_OCELOT_SWITCH
Depends on [n]: NETDEVICES [=y] && ETHERNET [=y] &&
NET_VENDOR_MICROSEMI [=n] && NET_SWITCHDEV [=y] && HAS_IOMEM [=y]
Selected by [y]:
NET_DSA_MSCC_FELIX [=y] && NETDEVICES [=y] && HAVE_NET_DSA [=y]
&& NET_DSA [=y] && PCI [=y]

This patch is to select NET_VENDOR_MICROSEMI for NET_DSA_MSCC_FELIX.
