[PATCH u-boot] MAC needs to be stopped after starting

[OpenBMC Patches]

From: Norman James <njames at us.ibm.com>

We found that u-boot network was corrupting kernel memory.
This is because aspeednic_init is called at startup,
but if the u-boot network is not used, the network driver
is not cleaned up.  This fix is a temporary hack and just calls
the halt function after the init. This driver needs to be
reworked to not start network initially and use set_hwaddr hook
to setup MAC address.
