1. Remove unnecessary new lines in the dts.
2. Remove duplicate included file "gpio.h" in the device dts.
3. Add missing button labels "reset" and "wps".
4. Unify the format of the reg properties.
5. Add u-boot environment support.
6. Reduce spi clock frequency since the max value suggested by the
chip datasheet is only 25 MHz.
7. Add seama header fixup for DIR-859 A1. Without this header fixup,
u-boot checksum for kernel will fail after the first boot.
