[U-Boot] [PATCH v4 8/8] mips: move optimize tuning option from deprecated config.mk to Kconfig

[Wills Wang]

config.mk files in mach-xxx directory are deprecated, this patch move
the processor tuning option of compiler into Kconfig

Changes in v4:
- Add div64 macro for MIPS
- Convert physical address to uncached and cached(KSEG0/1) memory range
  in map_physmem
- Auto calculate baudrate for serial driver
- Move pinctrl code in serial driver into arch/mips/mach-ath79
- Use global_data to save CPU/DDR/AHB clock
- Use get_serial_clock to serial clock source
- Use get_bus_freq instead of hardcode in SPI driver
- Use arch_global_data to save SOC's type, revison and id
- move CPU optimize tuning flag from config.mk to Kconfig

Changes in v3:
- Convert serial driver to driver model
- Convert spi driver to driver model
- Add support for device tree
- Move SoC specific header files into arch/mips/mach-ath79/include/mach
- Optimize assembly code
- Same code style convertion

Changes in v2:
- Move all SoC specific header files into arch/mips/include/asm/arch-ath79
- Check SOC type and extract common code into arch/mips/mach-ath79
- Add a compatible spi driver
- Move serial driver code into drivers/serial
- Add a reference board implemention
