next-20241015: drivers/of/address.c:244:31: error: passing 'const struct fwnode_handle *' to parameter of type 'struct fwnode_handle *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]

[Naresh Kamboju <naresh.kamboju@xxxxxxxxxx>]

A larger set of clang-19 builds failed on arm, mips, riscv and powerpc due to
following Linux next-20241015 tag and these include tinyconfig, allnoconfig etc.

And gcc-13 and gcc-12 builds are passed.

First seen on next-20241014
  GOOD: next-20241014
  BAD: next-20241015
