In order to clearly describe the dependencies between the GPIO
controller drivers and the users the driver is split up into a core,
two drivers and a common header.

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.

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.

Sparse (rightly) currently gives the following warning:
drivers/leds/simple/simatic-ipc-leds.c:155:40:
sparse: sparse: incorrect type in assignment (different address spaces)
expected void *static [toplevel] simatic_ipc_led_memory
got void [noderef] __iomem *
Fix this by changing the type of simatic_ipc_led_memory to void __iomem *
and use readl()/writel() to access it.

simatic_ipc_led_mem_res is not used outside of the driver, make it static.

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.
