    Partially Revert "of: fix sparse warnings in fdt, irq, reserved mem, and resolver code" · df3ed932

    A change to function pointers that was meant to address a sparse warning
    turned out to cause hundreds of new gcc-7 warnings:
    
    include/linux/of_irq.h:11:13: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]
    drivers/of/of_reserved_mem.c: In function '__reserved_mem_init_node':
    drivers/of/of_reserved_mem.c:200:7: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]
       int const (*initfn)(struct reserved_mem *rmem) = i->data;
    
    Turns out the sparse warnings were spurious and have been fixed in
    upstream sparse since 0.5.0 in commit "sparse: treat function pointers
    as pointers to const data".
    
    This partially reverts commit 17a70355.
