Fixes to 2 Capella light sensor drivers where the units of the integration time reported to userspace were out be a factor of a thousand. These patches are as large as they are purely due to a variable rename tied up with the incorrect scale. The actual change is only a couple of lines. 1 patch dropping L3GD20H from the st gyroscope driver. It never actually worked as the address set is different from any others supported by the driver currently. An additional patch enables correct support for this part but is too large to sensibly apply as a fix to some support that never actually allowed the driver to be successfully probed on this part.
