u-boot features and fixes, more kernel modules

1. Manually edited patch 0018-lx... to fix atheros phy related config.
2. Just before booting the kernel toggle back the fan full speed signal
to enable the kernel driver to initialize the AMC6821 device
3. Add u-boot poweroff command that set S5# (GPIO3 7) signal to low;
thus turning off the HoneyComb / ClearFog CX boards.

+Subject: [PATCH] lx2160acex7: add poweroff and disable fan full speed
+
+1. Add poweroff command; when using Clearfog CX or HoneyComb carrier
+boards, the S5# signal is connected to the power button controller that
+cuts off the '12v' supply from the COM module.
+
+2. In board_fix_fdt, just before booting the kernel the fan full speed
+signal becomes inactive so that the kernel AMC6821 driver would take
+over and enable the auto thermal and pwm adjustments.
