ramips: improve support for Xiaomi Miwifi Nano
This patch does the following things:
1. mark u-boot-env writable
2. add bootcount support
Currently, u-boot has a flag_boot_success env variable to reset.
Also reset it in our firmware to follow the behavior in vendor's
firmware.
3. disable usb support
This router doesn't have usb port at all.
4. increase spi clock to 40MHz
5. fix pinmux groups
