Subject: ACPI: Use fallthrough pseudo-keyword
Patch-mainline: v5.9-rc1
Git-commit: 57d2dd4bd18b1378b3bc0b6b2b8b858deb6c2fa7
References: jsc#SLE-16407
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.
