[U-Boot] [PATCH 2/2] IOMUX: Add console multiplexing support.

[Gary Jennejohn <garyj@denx.de>]

Since this patch touches net/eth.c it is being sent separately.

When CONFIG_IO_MUX, CONFIG_NETCONSOLE and CFG_CONSOLE_IS_IN_ENV are all
defined together it is possible that nc (netconsole) is defined as an
output device.  In this case it is necessary to set GD_FLG_DEVINIT
after the network devices have been initialized, otherwise u-boot
might try to send output to a device before it is ready, which leads
to various errors.
