Subject: [PATCH] Add missing header include <linux/mem_encrypt.h>

In commit c7753208a94c ("x86, swiotlb: Add memory encryption support") a
call to function ‘mem_encrypt_init’ was added. Include prototype
defined in header <linux/mem_encrypt.h> to prevent a warning reported
during compilation with W=1:

init/main.c:494:20: warning: no previous prototype for ‘mem_encrypt_init’ [-Wmissing-prototypes]
