thermal: msm_tsens: Check for valid status bit

Add support to read the temperature sensors valid
bit from the status register if present. This is to ensure
the last temperature data read from the status register is
a valid one. If the first read does not have a valid data
proceed to read the status register a max of three times
and choose the status code from the read that has the valid
bit set.

Also update the string of the efuse masks to align it with
the corresponding SoC's fusemap.
