x86: suppress HPET broadcast initialization in the presence of ARAT

This follows Linux commit 39fe05e58c5e448601ce46e6b03900d5bf31c4b0,
noticing that all this setup is pointless when ARAT support is there,
and knowing that on SLED11's native kernel it has actually caused S3
resume issues.

A question would be whether HPET legacy interrupts should be forced
off in this case (rather than leaving whatever came from firmware).
