ioat: convert ioat_probe to pcim/devm
The driver currently duplicates much of what these routines offer, so just use the common code. For example ->irq_mode tracks what interrupt mode was initialized, which duplicates the ->msix_enabled and ->msi_enabled handling in pcim_release. This also adds a check to the return value of dma_async_device_register, which can fail.
