dmaengine: ioatdma: use pci_dev_id() to simplify the code

PCI core API pci_dev_id() can be used to get the BDF number for a pci device. We don't need to compose it mannually. Use pci_dev_id() to simplify the code a little bit.

dmaengine: ioat: fixing the wrong dma_dev->chancnt

2023-08-21T13:08:19+00:00

The chancnt would be updated in __dma_async_device_channel_register(), but it was assigned in ioat_enumerate_channels(). Therefore chancnt has the wrong value. Add chancnt member to the struct ioatdma_device, ioat_dma->chancnt is used in ioat, dma_dev->chancnt is used in dmaengine.
