Changes since V2 :
- Remove boolean in intel_pxp_runtime_preapre for
non-pxp configs. Solves build error
Changes since V2 :
- Open-code intel_pxp_runtime_suspend - Daniele
- Remove boolean in intel_pxp_runtime_preapre - Daniele
Changes since V1 :
- split the HW access parts in gt_suspend_late - Daniele
- Remove default PXP configs
