MIPS: Lantiq: add SoC specific code for XWAY family
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.
