Enable the second PCIe port on QNAP TS-11x/TS-21x devices as newer
revisions (rev 1.3) have a USB 3.0 chip from Etron on PCIe port 1.

Now that the PCIe mvebu driver is usable on Kirkwood, use it instead
of the legacy PCIe code, since it allows to describe the PCIe
interfaces in the Device Tree.

When the pinmux mechanism was added in Kirkwood, the device driver
core was not yet providing the possibility of attaching pinmux
configurations to all devices, drivers had to do it explicitly, and
not all drivers were doing this.

Now that the driver core does that in a generic way, it makes sense to
attach the pinmux configuration to their corresponding devices.

This allows the pinctrl subsystem to show in debugfs to which device
is related which pins, for example:

pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41
pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42
pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43

Make use of the pinctrl driver for configuring all the pins, instead
of using the Orion mpp code.

The two different variants of QNAP TS devices, varying by SoC, put the
GPIO keys on different GPIO lines. Hence we need two different DT
board descriptions, which share the same board-ts219.c file.
