Reading the CFE properties causes system hangs on some devices. With
this patch nvram read will be successful very time so cfe will no be
read out. This code is not really correct but it will work around some
problems for some people.

* fix return codes of nvram_getenv. Now it behaves like cfe_getenv.
* also check cfe for kernel_args param.
* some style fixes

more and more users are getting confused by this, and consider it a regression in brcm47xx,
because brcm-2.4 was not showing this message. It's not particularly interesting for debugging,
most of the time it only happens because of an unconnected port.
