From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The variable val is having the top 8 bits cleared and then the variable is being
re-assinged and setting just the top 8 bits. I believe the intention was bitwise-or
in the top 8 bits. Fix this by replacing the = operators with &= and |= instead.
Addresses-Coverity: ("Unused value")
Fixes: b0c74b08517e ("drivers: thermal: processor_thermal_device: Export sysfs inteface for TCC offset")

V2: Add in &= operator missing from V1. Doh.
