baytrail: allow function disable on TXE
Previously it was not known how to put the TXE pci device
into D3Hot. It's been disseminated that this is not a requirement
for disabling the TXE pci device in the function disable register.
Therefore, allow this by returning 0 from place_device_in_d3hot().
BUG=chrome-os-partner:22871
BRANCH=None
TEST=Temporarily set TXE to be disabled. Noted FUNC_DIS was being
set accordingly.
