firmware: qcom_scm: Drop useless compatibles

There are three categories of compatibles within the driver:

1. Ones which were introduced without a qcom,scm fallback
2. Ones which were introduced with a qcom,scm fallback
3. Ones which were defined but never used

Keep 1 for backwards compatibility and axe 2 & 3.
