ueventd: allow platform devices to have just a /devices/ prefix - DO NOT MERGE

When using device tree, platform devices may not have a
/devices/platform/ path prefix, but can be rooted in
/devices/.

Modify the platform device tracking code to store the device
path as well as the name. This way, when we create symlinks, we
can correctly skip the base platform device prefix and get to the
proper device node path.

init: uevent: Add msm video symbolic link handling

Create meaningful symbolic links for video encode/decode
devices based on link_name sysfs node so that video client
doesn't have to rely on dynamic dev node names like device32,
device33 etc.
