When compile FSL_DPAA2_SWITCH, it needs to set CONFIG_FSL_DPAA2_ETH=y,
otherwise it cannot be compiled.
And as Ioana Ciornei sugggested, FSL_DPAA2_SWITCH included dpaa2-mac.o in
the driver, but it does not select PCS_LYNX, PHYLINK and FSL_XGMAC_MDIO

v1->v2
There is no code dependency between the dpaa2-switch driver and the
dpaa2-eth, so use Makefile to control dpaa2-eth instead of using depending
on in Kconfig.
And add select PCS_LYNX, PHYLINK and FSL_XGMAC_MDIO for FSL_DPAA2_SWITCH.

Cai Xinchen (2):
  dpaa2: add select config for FSL_DPAA2_SWITCH
  dpaa2: compile dpaa2 even CONFIG_FSL_DPAA2_ETH=n
