[OE-core] [PATCH v2 0/4] Busybox mdev improvements

[Mike Looijmans]

I've been using busybox mdev instead of udev in many projects, which so
far has worked excellently.

Each of these projects needed similar patches to busybox to make it work,
so I think its time these changes move into the core for everyone to use.

v2: I joined the two patch sets together.
The first two fix the touchscreen support.
The third makes the system automatically load kernel modules when
you plug in a device.
The fourth adds automounter capabilities. In v2 the default location is
/run/media, which can be changed in /etc/default/mdev.
