The RCU register are now access through separates drivers. remove the
last pieces of the old implementation.

The GPHY reset bits are now set by the GPHY driver which registers a
reboot notifier. The reboot is triggered by a syscon-reboot driver and
the MIPS specific parts are done by the generic MIPS implementation in
arch/mips/kernel/reset.c.

Now it is possible to build in no device tree at all and depend on the
boot loader providing one or someone concatenating a device tree to the
end of the image.

Move the Lantiq device-trees to arch/mips/boot/dts/ and update the
Makefiles accordingly.  There is currently only a single Lantiq
device-tree (EASY50712), and it's required to be built into the kernel,
so select BUILTIN_DTB for it.

The internal GPHYs need a firmware blob to function properly. This patch adds
the code needed to request the blob and load it to the PHY.

Implement support for pinctrl on lantiq/xway socs. The IO core found on these
socs has the registers for pinctrl, pinconf and gpio mixed up in the same
register range. As the gpio_chip handling is only a few lines, the driver also
implements the gpio functionality. This obseletes the old gpio driver that was
located in the arch/ folder.

Add support for the Lantiq XWAY family of Mips24KEc SoCs.

* Danube (PSB50702)
* Twinpass (PSB4000)
* AR9 (PSB50802)
* Amazon SE (PSB5061)

The Amazon SE is a lightweight SoC and has no PCI as well as a different
clock. We split the code out into seperate files to handle this.

The GPIO pins on the SoCs are multi function and there are several bits
we can use to configure the pins. To be as compatible as possible to
GPIOLIB we add a function

int lq_gpio_request(unsigned int pin, unsigned int alt0,
        unsigned int alt1, unsigned int dir, const char *name);

which lets you configure the 2 "alternate function" bits. This way drivers like
PCI can make use of GPIOLIB without a cubersome wrapper.

The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was
taken from a 2.4.20 source tree and was never really changed by me since then.
