fsl_pci_ep: update fsl_pci_ep.c according to kernel changes

1. Now in kernel the dev_attrs field is removed from struct class,
and is converted to use dev_groups. So the patch uses pci_ep_groups
instead of pci_ep_attrs.
2. The field pci_mem_offset of struct pci_controller has been
changed to mem_offset[], so the patch update the related code.
3. Remove is_pcie initialization for this field has been removed
from struct pci_dev.
