[PATCH 46/46] of: reserved_mem: Delete the fdt_init_reserved_mem() function

From: Oreoluwa Babatunde
Date: Fri Jan 26 2024 - 19:04:01 EST


Delete the fdt_init_reserved_mem() function as all architectures have
been switched to using dt_init_reserved_mem(), which is basically a copy
of the function, but uses the unflatten devicetree APIs instead of the
fdt APIs.
