hwmon: (tps23861) fix byte order in current and voltage registers
Trying to use this driver on a big-endian machine results in garbage
values for voltage and current. The tps23861 registers are little-
endian, and regmap_read_bulk() does not do byte order conversion. Thus
on BE machines, the most significant bytes got modified, and were
trimmed by the VOLTAGE_CURRENT_MASK.
To resolve this use uint16_t values, and convert them to host byte
order using le16_to_cpu(). This results in correct readings on MIPS.
