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 17a70355ea576843a7ac851f1db26872a50b2850.
Fixes: 17a70355ea57 ("of: fix sparse warnings in fdt, irq, reserved mem, and resolver code")
