[U-Boot] [PATCH 5/9] powerpc/mpc8548cds: Fix network initialization

[Zhao Chenhui]

From: chenhui zhao <chenhui.zhao at freescale.com>

Add board_eth_init(). PCIe network card is also supported.
Put RGMII init after tsec_eth_init().
Skip initializing eTSEC3 and eTSEC4 with Carrier boards prior to ver 1.3.
