With CONFIG_DM_ETH enabled, aquantia driver compilation fails with below error. This patch fixes the issue by including dm.h.

drivers/net/phy/aquantia.c: In function ‘aquantia_startup’: drivers/net/phy/aquantia.c:73:21: error: dereferencing pointer to incomplete type ‘struct udevice’ phydev->dev->name); ^~

This patch adds PFE driver to U-Boot

Following are the main driver files:- pfe_hw.c: provides low level helper functions to initialize PFE internal processor engines and other hardware blocks pfe_driver.c: provides initialization functions and packet send and receive functions pfe_eth.c: provides high level gemac initialization functions pfe_firmware.c: provides functions to load firmware into PFE internal processor engines. pfe_mdio.c: provides functions to initialize phy and mdio.
