HV: remove function pci_pdev_foreach()
And make other related changes accordingly: Remove pci_pdev_enumeration_cb define Create init_vdevs() to iterate through the pdev list and create vdev for each pdev Export num_pci_pdev and pci_pdev_array as globals in header file Minor cosmetic fix: Remove trailing whitespace Tracked-On: #3022 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> Reviewed-by: Eddie Dong <eddie.dong@intel.com>
