ipq40xx: add support for Crisis Innovation Lab MeshPoint.One

MeshPoint.One is Wi-Fi hotspot and smart IoT gateway (based upon
Jalapeno module from 8Devices).

MeshPoint.One (https://meshpointone.com) is a unique Wi-Fi hotspot and
smart city gateway that can be installed and powered from street
lighting (even solar power in the future).  MeshPoint provides up to 27
hours of interrupted Wi-Fi and IoT services from internal battery even
when external power is not available.  MeshPoint.One can be used for
disaster relief efforts in order to provide instant Wi-Fi coverage that
can be easily expanded by just adding more devices that create wide area
mesh network.  MeshPoint.One devices have standard Luci UI for
management.

Features:
- 1x 1Gpbs WAN
- 1x 1Gbps LAN
- POE input (eth0)
- POE output (eth1)
- Sensor for temperature, humidity and pressure (Bosch BME280)
- current, voltage and power measurement via TI INA230
- Hardware real time clock
- optional power via Li-Ion battery
- micro USB port with USB to serial chip for easy OpenWrt terminal
  access
- I2C header for connecting additional sensors

Installation:
-------------
Simply flash the sysupgrade image from stock firmware.

Or use the built in Web recovery into bootloader:
Hold Reset button for 5 to 20 seconds or use UART and httpd command.
Web UI will appear on 192.168.2.100 by default.
For web recovery use the factory.ubi image.
