[Letux-kernel] letux-4.11-rc1

Hi,
I have upgraded the tree and fixed some merge & compile issues.

But I have trouble booting:

If someone finds a little time, please check if you also have this.

Before we put too much efforts into this, let's await -rc2 because
this may be issues others have as well.

There are also some issues with bluetooth since I have switched from
our w2sg0004 driver to the new serdev driver. This also disables the
w2cbw bluetooth driver. Maybe we need to implement some serdev
based driver for BT as well...

BR,
Nikolaus
