raw/ioat: fix build when ioat dmadev enabled

The build of the raw/ioat driver only occurs when the equivalent dmadev
drivers are disabled. Complications occur when the ioat dmadev is being
built but not the idxd. In this case, only the idxd part of raw/ioat
gets built, but the definition of the logtype is in the ioat part,
causing build errors.

  .../raw_ioat_idxd_bus.c.o: In function `idxd_vdev_mmap_wq':
  idxd_bus.c:(.text+0x116): undefined reference to `ioat_pmd_logtype'

Fix this by moving the logtype definition to the common C file, and
renaming it to avoid conflicts with a similarly named value in the
dma/ioat driver.
