of/fdt: move elfcorehdr reservation early for crash dump kernel
[ Upstream commit 132507ed04ce0c5559be04dd378fec4f3bbc00e8 ]
elfcorehdr_addr is fixed address passed to Second kernel which may be conflicted
with potential reserved memory in Second kernel,so fdt_reserve_elfcorehdr() ahead
of fdt_init_reserved_mem() can relieve this situation.
