Subject: [PATCH][next] PCI: imx6: Use fallthrough pseudo-keyword

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Thu, 16 Jul 2020 16:10:52 -0500

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.
