This patch unifies all clock generation and gating code into one file.
All drivers will now be able to request their clocks via their device.
This patch also adds support for the clockout feature, which allows
clock generation on external pins.
Support for COMMON_CLK will be provided in the next series.

As part of the conversion to OF we also implement pinctrl drivers. Previously
we used ltq_gpio_request() to set pinmuxing. This is now obselete and we can
hence drop the function.
Additionally we remove gpio_to_irq() from the gpio driver and move it to a
header file.

Before we are able to add OF support, we really want to drop all the bloat
needed to register all the platform devices.

Add the soc ids for additional xway socs. The patch also merges the amazon_se

Panic() invokes printk() to add a \n internally, so panic arguments should
not themselves end in \n. Panic invocations in arch/mips and elsewhere
are inconsistently sometimes terminating in \n, sometimes not.

It was pointed out by 'make versioncheck' that some includes of
linux/version.h are not needed in arch/mips/.
This patch removes them.

This patch adds the driver for the ETOP Packet Processing Engine (PPE32)
found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit
ethernet work. Support for all 8 dma channels, gbit and the embedded switch
found on the ar9/vr9 still needs to be implemented.

The XWAY family allows to extend the number of gpios by using shift
registers or latches. This patch adds the 2 drivers needed for this. The
extended gpios are output only.

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.
