[PATCH v2 0/6] usb: Migrate drivers to use dev/ofnode APIs

[Peng Fan (OSS)]

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.
