Avoid arbitrarily reducing ZHA climate temperature information (#43442) 

The Zigbee specification mandates that temperatures are given in
1/100ths of degrees, and several devices are able to provide temperature
readings or accept target temperature settings with precision equal or
better than 0.1°C. Yet the ZHA climate entity implementation advertises
an hard-coded precision of 0.5°C.

Avoid arbitrary coarsening by advertising 0.1°C precision, as passing
through the full 0.01°C precision is probably not that useful.
