The TMU (Thermal Monitoring Unit) on the i.MX93 requires specific
configurations and workarounds that differ from previous implementations.
So, using the 'fsl,qoriq-tmu' compatible string is not appropriate.
To address this, a dedicated compatible string and corresponding driver
changes need to be introduced to properly support the i.MX93 TMU.
