sensor: fix proximity sanity tests issues

When the proximity sensor was not well configured the thresholds has
been lowered to 0x60 in a range of (0x0 -> 0x3ff) measured data.
This threshold has to be increased to 0x100 as for some devices (DVT)
the reported data for a far distance corresponds to a value near 0xa0
