MIPS: Loongson: Add basic Loongson 2F support
Loongson 2F has built-in DDR2 and PCI-X controller. The PCI-X controller has a programming interface similiar to the the FPGA northbridge used on Loongson 2E. The main differences between Loongson 2E and Loongson 2F include: 1. Loongson 2F has an extra address window configuration module, which is used to map CPU address space to DDR or PCI address space, or map the PCI-DMA address space to DDR or LIO address space. 2. Loongson 2F supports 8 levels of software configurable CPu frequency which can be configured in the LOONGSON_CHIPCFG0 register. The coming cpufreq and standby support are based on this feature. Loongson.h abstracts the modules and corresponding methods are abstracted. Add other Loongson-2F-specific source code including gcc 4.4 support, PCI memory space, PCI IO space, DMA address.
