soc: fsl: cpm1: qmc: Add support for QUICC Engine (QE) implementation

Add support for the QMC (QUICC Multichannel Controller) available in
some PowerQUICC SoC that uses a QUICC Engine (QE) block such as MPC8321.

This QE QMC is similar to the CPM QMC except that it uses UCCs (Unified
Communication Controllers) instead of SCCs (Serial Communication
Controllers). Also, compared against the CPM QMC, this QE QMC does not
use a fixed area for the UCC/SCC parameters area but it uses a dynamic
area allocated and provided to the hardware at runtime.
