thermal: imx_tmu: Move architecture code into driver

Stop polluting the architecture directory with driver specific code,
move it into driver where it should be. Split the code slightly so
the MX8MM/MX8MN fuse readout and programming and MX8MP fuse readout
and programming are in their separate functions, and called in case
of matching SoC.
