[PATCH net-next] net: dsa: vsc73xx: Fix Kconfig warning and build errors

[YueHaibing <yuehaibing@huawei.com>]

Fix Kconfig dependency warning and subsequent build errors
caused by OF is not set:

WARNING: unmet direct dependencies detected for NET_DSA_VITESSE_VSC73XX
  Depends on [n]: NETDEVICES [=y] && HAVE_NET_DSA [=y] && OF [=n] && NET_DSA [=m]
  Selected by [m]:
  - NET_DSA_VITESSE_VSC73XX_PLATFORM [=m] && NETDEVICES [=y] && HAVE_NET_DSA [=y] && HAS_IOMEM [=y]

Move OF and NET_DSA dependencies to NET_DSA_VITESSE_VSC73XX/
NET_DSA_VITESSE_VSC73XX_PLATFORM to fix this.
