libfdt: Make fdt_string() return a const pointer
From: David Gibson <hidden>

Currently, fdt_string() returns a (non-const) char *, despite taking a const void *fdt. This is inconsistent with all the other read-only functions which all return const pointers into the blob. This patch fixes that. Signed-off-by: David Gibson <redacted> Index: dtc/libfdt/fdt_ro.c ===================================================================
