linux-yocto: fix qemux86-64 config warning

During the 3.19 update a 32 bit option in the 64 bit config was missed,
which results in the option being dropped (and reported as a warning):

  Value requested for CONFIG_PCI_GOANY not in final ".config"
  Requested value: "CONFIG_PCI_GOANY=y"
  Actual value set: ""

So we split the 32bit only drivers out of the common driver include and
the problem goes away.
