For apollolake the mapping between LEDs and GPIO pins was off because of
a refactoring when we introduced a new device model.
In addition to the reordering the indices in the lookup table need to be
updated as well.

simatic_ipc_led_gpio_table is only used inside simatic-ipc-leds-gpio.c,
make it static.

This adds support of the Siemens Simatic IPC227G. Its LEDs are connected
to GPIO pins provided by the gpio-f7188x module. We make sure that
gets loaded, if not enabled in the kernel config no LED support will be
available.

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.

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.
