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]
