ENGR00139198: iMX61 uBoot add ENET support
Add ENET and AR8031 PHY support to uboot.
To make it works on sabreauto, need do following changes:
1. rework phy to output 125M clock from CLK_25M signal,
and the 125M clock input to SoC as reference clock to generate
RGMII_TXC clock.
2. Enable TXC delay in PHY debug register.
3. set ENET working in RMII mode.
4. set ENET working at 1000M or 100M/10M.
5. set ENET TX fifo to maximum to avoid underrun error.
6. force AR8031 PHY working at 100M
