firmware: imx: scu-pd: Add mu13 b side PD range
LSIO subsystem contains 14 MU instances.
5 MUs to communicate between AP <-> SCU
- side-A PD range managed by AP
- side-B PD range managed by SCU
9 MUs to communicate between all cores (AP/M4/DSP).
- side-A PD range managed by core-A (AP/M4/DSP)
- side-B PD range managed by core-B (AP/M4/DSP).
Communication between AP <-> DSP is done through the
assigned MU number 13.
So, we power up side-A by the AP and we decide to
power up side-B also from AP. This is because powering
it up from DSP would be painful.
Powering up side B from DSP would require the DSP to
communicate with SCU and to keep things simple we don't
want that now.
