efi: fix missing prototype warnings
Commit Message
From: Arnd Bergmann <arnd@arndb.de>
The cper.c file needs to include an extra header, and
efi_zboot_entry needs an extern declaration to avoid these
'make W=1' warnings:
drivers/firmware/efi/libstub/zboot.c:65:1: error: no previous prototype for 'efi_zboot_entry' [-Werror=missing-prototypes]
drivers/firmware/efi/efi.c:176:16: error: no previous prototype for 'efi_attr_is_visible' [-Werror=missing-prototypes]
drivers/firmware/efi/cper.c:626:6: error: no previous prototype for 'cper_estatus_print' [-Werror=missing-prototypes]
drivers/firmware/efi/cper.c:649:5: error: no previous prototype for 'cper_estatus_check_header' [-Werror=missing-prototypes]
drivers/firmware/efi/cper.c:662:5: error: no previous prototype for 'cper_estatus_check' [-Werror=missing-prototypes]

Yuck. Could we move the missing definitions to linux/cper.h instead?
