hwmon: (adt7475) Fix masking of hysteresis registers
The wrong bits are masked in the hysteresis register; indices 0 and 2
should zero bits [7:4] and preserve bits [3:0], and index 1 should zero
bits [3:0] and preserve bits [7:4].
Fixes: 1c301fc5394f ("hwmon: Add a driver for the ADT7475 hardware monitoring chip")
