ddr: altera: Add DDR driver for Agilex7 M-series
This is for new platform enablement for Agilex7 M-series.
Add DDR driver for Agilex7 M-series. This driver is designed to support
DDR and HBM memory. The official HBM handoff is not ready yet, therefore
hardcoded handoff is used for HBM driver validation on mUDV board.
