thermal/drivers/imx: Add support for loading calibration data from OCOTP

The TMU TASR, TCALIVn, TRIM registers must be explicitly programmed with
calibration values in OCOTP. Add support for reading the OCOTP calibration
data and programming those into the TMU hardware.

The MX8MM/MX8MN TMUv1 uses only one OCOTP cell, while MX8MP TMUv2 uses 4,
the programming differs in each case.

Based on U-Boot commits:
70487ff386c ("imx8mm: Load fuse for TMU TCALIV and TASR")
ebb9aab318b ("imx: load calibration parameters from fuse for i.MX8MP")
