At present the board supports non-DM version PCI and E1000 drivers. Switch over to use DM ETH and PCI by:
- Rewrite the PCI address map functions using DM APIs - Enable CONFIG_MISC_INIT_R to do the PCI initialization and address map - Drop unnecessary ad-hoc config macros - Remove board_eth_init() in the board codes
