a6c80bec3c leds: simatic-ipc-leds-gpio: Add GPIO version of Siemens driver 
On Apollo Lake the pinctrl drivers will now come up without ACPI. Use
that instead of open coding it.
Create a new driver for that which can later be filled with more GPIO
based models, and which has different dependencies.

759273c3c4 leds: simatic-ipc-leds: Convert to use P2SB accessor 
Since we have a common P2SB accessor in tree we may use it instead of
open coded variants.

Replace custom code by p2sb_bar() call.

8c78e0614e leds: simatic-ipc-leds: add new driver for Siemens Industial PCs 
This driver adds initial support for several devices from Siemens. It is
based on a platform driver introduced in an earlier commit.

One of the supported machines has GPIO connected LEDs, here we poke GPIO
memory directly because pinctrl does not come up.
