Subject: [PATCH] ramips: improve support for Zyxel Keenetic Extra II

- drop unneeded default-state for led_power
- concat firmware partitions to extend available free space
- increase spi flash frequency to 32 Mhz (value from stock firmware bootlog)
- drop broken-flash-reset because of onboard flash chip W25Q256FV has reset support
- add compatible for pcie wifi according to kernel documetation
- switch to wan mac address with offset 0x28 in rf-eeprom
