[PATCH 1/1] s390/ipl: Fix missing arch_get_secureboot() prototype warning

[Vasily Gorbik]

Include <linux/secure_boot.h> so arch_get_secureboot() has a visible
prototype and -Wmissing-prototypes no longer triggers.

arch/s390/kernel/ipl.c:2507:6: warning: no previous prototype for 
‘arch_get_secureboot’ [-Wmissing-prototypes]
 2507 | bool arch_get_secureboot(void)
      |      ^~~~~~~~~~~~~~~~~~~

Fixes: 63e8a44395a4 ("integrity: Make arch_ima_get_secureboot integrity-wide")
