[PATCH] x86: fix non-static inlines

[Denys Vlasenko]

Four instances of incorrect usage of non-static "inline" crept up
in arch/x86, all trivial; cleaning them up:

EVT_TO_HPET_DEV() - made static, it is only used in kernel/hpet.c

Debug version of check_iommu_entries() is an __init function.
Non-debug dummy empty version of it is declared "inline" instead -
which doesn't help to eliminate it (the caller is in a different unit,
inlining doesn't happen).
Switch to non-inlined __init function, which does eliminate it
(by discarding it as part of __init section).

crypto/sha-mb/sha1_mb.c: looks like they just forgot to add "static"
to their two internal inlines, which emitted two unused functions into
vmlinux.
