[yocto] [PATCH] runtime: add BSP test case for usb storage

[mohamad.noor.alim.hussin at intel.com]

From: Mohamad Noor Alim Hussin <mohamad.noor.alim.hussin at intel.com>

Contain test cases to test mount/unmount the usb stick on target
platform such as minnowboard and beaglebone. The test assume that
the usb storage device such as usb thumb drive was plugged into
the target device otherwise the test for would failed. It also test
to read and write from usb thumb drive. Usb test cases start with
mount the usb thumb drive then write and read from it. Lastly, it
will unmount it. If the usb thumb drive unable to mount due to corrupt
of partition or not exists, then the mount test will failed and the
following test would skip.

This test need to enable flag 'HARDWARE_TEST = "1"' on conf/local.conf
file in order to run on target device. This test should be skip on qemu.
