libnetutils: Fix up the dhcp request arguments

The interface/config-file arguments passed to the dhcpcd invocation
when a hostname isn't provided were swapped, causing requests to be made
for interface <config-file-name> instead of <interface-name>, and
failing all calls to start dhcpcd through netutils with the following error:

E/DhcpStateMachine( 3214): DHCP failed on wlan0: Timed out waiting for dhcpcd to start

because...

<3>[  582.717015] init: no such service 'dhcpcd_/system/etc/dhcpcd/dhcpcd.conf:-f wlan0 wlan0'

Init: Allow building of init that is compatible with second init boot

When using second init init has already set up /dev /proc, etc
this will prevent duplicate mount points for those
Define BOARD_USE_NO_DEVFS_SETUP := true to use

Allow for use of custom init code for device alias

Motorola OMAP4 devices do not use the standard /dev/block/platform/omap/*/by-name/* references
Instead the init binary creates symlinks at startup for several of the main partitions
Set BOARD_USE_MOTOROLA_DEV_ALIAS := true to use this feature
