[meta-freescale] [meta-fsl-demos][PATCH 2/3] sysvinit: auto detect hostname for qoriq machines

[Zhenhua Luo]

If a rootfs only contains core specific pkgs (no machine specific
ones), it is convenient and possible to share a common rootfs image
for all the machines with same core.

Add a patch (only works for fsl qoriq boards) to auto set hostname.

Also add support to set hostname via bootargs/cmdline.
