Subject: [PATCH 2/2] hwmon: lm75: Add another name for NXP LM75B to of_match list

NXP LM75B is compatible with original LM75A while it has improved
11-bit precision.

https://www.nxp.com/docs/en/data-sheet/LM75B.pdf

NXP LM75B support was added in

    799fc6021430 ("hwmon: (lm75) Add support for the NXP LM75B")

OF compatible string "national,lm75b" for LM75B was created in

    e97a45f1b460 ("hwmon: (lm75) Add OF device ID table")

Since the previous commit introduces "nxp,lm75a" compatible string
for LM75A, there is a reason to add another alias for LM75B.
