[PATCH] kexec: include asm/early_ioremap.h

[Arnd Bergmann <arnd@kernel.org>]

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);
      |               ^

Fixes: 4bfe738ce89a ("kexec: add KHO support to kexec file loads")
