Changes in v4:
-Compile pfe driver conditionally with CONFIG_FSL_PFE

Changes in v3:
-Update Kconfig
-Update header file location to include/net/pfe_eth
-Prefix CONFIG_PFE_ to appropriate macros

Changes in v2:
-split from original patch "board: freescale: ls1012a: enable network
support on ls1012a platforms"
