hwmon: (tps23861) fix byte order in resistance register

commit 1f05f65bddd6958d25b133f886da49c1d4bff3fa upstream.

The tps23861 registers are little-endian, and regmap_read_bulk() does
not do byte order conversion. On BE machines, the bytes were swapped,
and the interpretation of the resistance value was incorrect.

To make it work on both big and little-endian machines, use
le16_to_cpu() to convert the resitance register to host byte order.
