For QM/QXP, the 4 power domains are: DSP, DSP_RAM, MU13A, MU13B. First off, drop MU13A from the count. This is attached to the platform device of lsio_mu13. This decreases the count to 3. Secondly, drop DSP and DSP_RAM from the count for QXP. These are attached to the platform devices of the lpcgs (used as clock providers for the DSP). With this in mind, the number of required power domains for QXP is 1 (MU13B), while for QM it's 3 (MU13B, DSP, DSP_RAM). Additionally, two extra power domains may be required in the case of QM/QXP DSPs. These are IRQSTR_DSP and MU2A. For the nodes using the "-hifi4" compatibles these PDs are optional, while for nodes using the "-dsp" compatibles these are mandatory. These changes reflect all of this information.
