Vivek Pernamitta 54c67740ff bus: mhi: host: pci_generic: Set DMA mask for VFs ...

VFs in devices like QDU100 are capable of accessing host memory up to 40
bits, compared to 32 bits used by PFs and other non-SR-IOV capable MHI
devices.

To support this, configure `dma_mask` independently for PFs and VFs, by
introducing a new 'vf_dma_data_width' member in 'mhi_pci_dev_info' struct
and set it to 40 for QDU100.
