[PATCH 1/1] scripts/dtc: avoid discarded qualifiers in overlay_fixup_phandle

[Heinrich Schuchardt]

When building with GCC 15.2 the following warning show up:

    scripts/dtc/libfdt/fdt_overlay.c:422:21: warning:
    assignment discards ‘const’ qualifier from pointer target type
    [-Wdiscarded-qualifiers]
      422 |                 sep = memchr(fixup_str, ':', fixup_len);
          |                     ^
    scripts/dtc/libfdt/fdt_overlay.c:432:21: warning:
    assignment discards ‘const’ qualifier from pointer target type
    [-Wdiscarded-qualifiers]
      432 |                 sep = memchr(name, ':', fixup_len);
          |                     ^

Define sep as const char *.
