x86: disable hpet on shutdown
If HPET was enabled by pci quirks, we use i8253 as initial clockevent
because pci quirks doesn't run until pci is initialized.
The above means the kernel (or something) is assuming HPET legacy
replacement is disabled and can use i8253 at boot.
If we used kexec, it isn't true. So, this patch disables HPET legacy
replacement for kexec in machine_shutdown().
