Add a dedicated binding for the Qualcomm Nord SoC PAS devices: ADSP
and CDSPs. Nord ADSP uses CX and MX power domains while the CDSPs
add an NSP domain on top of that.

Add support for ADSP (HPASS DSP) and 4 CDSPs found on Nord SoC. The ADSP
is pre-booted by XBL before Linux starts, so set early_boot flag for
attach path rather than a cold boot sequence.
