Despite the "leds: simatic-ipc-leds-gpio: add new model 227G" missing
an ack from the LED subsys maintainers I have decided to move forward
with this.

The LED changes in that patch are quite small / trivial, it actually
touches both drivers/leds and drivers/platform/x86 and the latter
changes are bigger and it also has been Reviewed by both me and Andy.
So I'm going for the it is easier to ask for forgiveness then ...
route here wrt the missing LEDs subsys ack.

I've just pushed a new platform-drivers-x86-simatec branch which
contains 6.0-rc1 + these 7 patches.

Next I'm to send out a pull-req (based on a signed tag)
to the involved subsys maintainers and merge that signed tag into
my review-hans branch (and from there it will go to pdx86/for-next).

Regards,

Hans
