[Yuntao Wang <yuntao.wang@linux.dev>]

This patch series fixes several bugs related to dt_root_addr_cells and
dt_root_size_cells, and performs some cleanup.

Changelog:

v2 -> v3:
  - Use of_flat_dt_ instead of of_fdt_ as the prefix for the newly added
    helper functions

  - Improve the internal logic of of_flat_dt_get_addr_size_prop() and
    of_flat_dt_get_addr_size()

  - Introduce the entry_index parameter for of_flat_dt_read_addr_size()

  - Fix some warnings and coding-style issues

v1 -> v2:
  - Consolidate duplicate code into helper functions
