Laurentiu Mihalcea 8a85a9aade dt-bindings: dsp: fsl,dsp: fix power domain count
Per the current binding, QM/QXP DSPs are supposed to have 4
power domains, while the rest just 1. For QM/QXP, the 4 power
domains are: DSP, DSP_RAM, MU13A, MU13B.

First off, drop MU13A from the count as its already attached
to lsio_mu13. This decreases the count to 3.

Secondly, drop DSP and DSP_RAM from the count for QXP. These
are already attached to the DSP's LPCGs.

Thirdly, a new power domain is required for DSP-SCU communication
(MU2A). With this in mind, the number of required power domains
for QXP is 2 (MU2A, MU13B), while for QM it's 4 (MU13B, DSP,
DSP_RAM, MU2A).

Update the fsl,dsp binding to reflect all of this information.
Since the arm,mhuv2 binding has an example node using the
fsl,imx8qxp-dsp compatible, remove two of the extra PDs to
align with the required power domain count.
