[PATCH 1/2] kernel-stub: Avoid warnings when converting buffer addresses to pointers

[Jan Kiszka]

From: Jan Kiszka <jan.k...@siemens.com>

On 32-bit systems, we get "cast to pointer from integer of different
size" warnings. Silence then which we can safely do because the
fdt_buffer will not exceed 32 bits, being provided by AllocatePages().
