Subject: [PATCH v3 1/2] ima: fix build error redeclaration of enumerator

Commit a893ea15d764 ("tpm: move tpm_chip definition to
include/linux/tpm.h") introduced a build error when both ima and efi is
enabled. What happens is that both headers (ima.h and efi.h) defines the
same 'NONE' constant, and it broke when they started getting included
from the same file.
