[Peter Maydell]

From: Patrick Venture <venture@google.com>

Add the four lm75s behind the mux on bus 13.

Tested by booting the firmware:
lm75 42-0048: hwmon0: sensor 'lm75'
lm75 43-0049: supply vs not found, using dummy regulator
lm75 43-0049: hwmon1: sensor 'lm75'
lm75 44-0048: supply vs not found, using dummy regulator
lm75 44-0048: hwmon2: sensor 'lm75'
lm75 45-0049: supply vs not found, using dummy regulator
lm75 45-0049: hwmon3: sensor 'lm75'
