From: Arnd Bergmann <arnd@arndb.de>

The early_memremap() function is decleared in a header that is only indirectly
included here:

kernel/kexec_handover.c:1116:8: error: call to undeclared function 'early_memremap'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
1116 | fdt = early_memremap(fdt_phys, fdt_len);
| ^
