Convert several USB drivers to use the dev_* and ofnode_* APIs and removes dependency on fdt/devfdt helpers.
The motivation is to: - Eliminate direct usage of gd->fdt_blob and fdtdec_* interfaces - Avoid devfdt_* helpers in favor of backend-agnostic APIs - Ensure compatibility with both live device tree and flat DT Summary: - Clean up unused legacy variables - Convert MUSB driver to use dev_* and ofnode_* APIs - Improve phandle parsing with proper validation - Replace devfdt_remap_addr_* with dev_remap_addr_* in MTK and MTU3 - Replace devfdt_get_addr_* with dev_read_addr_* in MVEBU Not have the boards to test mainly regarding the musb changes, just best practice for the migration.
