partition mount is broken for JellyBean4.2

[Yongqin Liu]

The system partition is not mount correctly for JellyBean4.2.
like:
https://validation.linaro.org/lava-server/scheduler/job/40324/log_file

This is because the partition mount information is moved to fstab.properties file
And here is some information from bhoj:

<liuyq> bhoj, do all the boards use the fstab.partitions file to mount, or they use separate file?
<bhoj> liuyq, can you parse fstab.* file
<bhoj> liuyq, we will be adding a cleanup to look at fstab.<ro.hardware> which would map to fstab.omap4pandaboard fstab.origen etc .
<liuyq> bhoj, ok, I see. but for now, it is just the fstab.partitions file right?
<bhoj> liuyq, yes
<liuyq> bhoj, do you have plan when will change to use fstab.<ro.hardware>?
<bhoj> liuyq, sometime in 12.12 .
<liuyq> bhoj, ok, will check if we can change to support that easily

Hope the modification of this can be deployed as soon as possible.
otherwise we can not do the test jobs with lava.

The above error is not related to this bug.

[ 5.922668] EXT4-fs (mmcblk0p6): mounted filesystem with ordered data mode. Opts: nomblk_io_submit,errors=panic
is information from the first boot, and there are some test executed after that,
so we can consider this information as not a problem

And the job is failed due to the failure of the boot_linaro_android_image action.
after run "netcfg eth0 dhcp", there was no response returned.
