imx8mp: Add fused parts support
iMX8MP has 6 fused parts in each qualification tier, with core, VPU,
ISP, NPU or DSP fused respectively.
The configuration tables for enabled modules:
MIMX8ML8DVNLZAA Quad Core, VPU, NPU, ISP, DSP
MIMX8ML7DVNLZAA Quad Core, NPU, ISP
MIMX8ML6DVNLZAA Quad Core, VPU, ISP
MIMX8ML5DVNLZAA Quad Core, VPU
MIMX8ML4DVNLZAA Quad Lite
MIMX8ML3DVNLZAA Dual Core, VPU, NPU, ISP, DSP
Add the support in U-Boot
