[Xen-devel] [PATCH] qemu-dm: pass-through: fix header type register emulation.

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

This patch fixes the emulation of latency timer and header type.
The change set of cc1a204423475ff7a918b11d78b9ae637f320e23
deleted the header type register emulation.
On the other hand, the change set of ec5e52d5cb2e6f8851c345b7c3095fe2030fff9c
tries to update header type emulation, however it wrongly 
touches latency timer emulation part.
I think this was caused by mis-merging. This patch sorts it out.
