Add bindings for adp810 differential pressure and temperature
sensor. This sensor communicates over I2C with CRC support and
can measure pressure in the range -500 to 500Pa and temperature
in the range -40 to +85 degree celsius.

+description:
+ ADP810 is differential pressure and temperature sensor. It has I2C bus
+ interface with fixed address of 0x25. This sensor supports 8 bit CRC for
+ reliable data transfer. It can measure differential pressure in the
+ range -500 to 500Pa and temperate in the range -40 to +85 degree celsius.
