fdt_support: add 'const' qualifier for unchanged argument
In the next commit, I will add a new function, fdt_pack_reg() which uses get_cells_len(). Beforehand, this commit adds 'const' qualifier to get_cells_len(). Otherwise, a warning message will appear: warning: passing argument 1 of 'get_cells_len' discards 'const' qualifier from pointer target type [enabled by default] Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>
