[patch-mm 15/23] x86_64: untangle asm/hpet.h from asm/timex.h

[Thomas Gleixner]

From:	Chris Wright <chrisw@xxxxxxxxxxxx>

When making changes to x86_64 timers, I noticed that touching
hpet.h triggered an unreasonably large rebuild.  Untangling
it from timex.h quiets the extra rebuild quite a bit.
