dongshen 82789f44a9 HV: declare and export partition mode's vdev functions as global instead of static local
Export the following functions as global instead of static so that they can be
called/referred outside of the files where they are declared:

vdev_pt_init
vdev_pt_deinit
vdev_pt_cfgread
vdev_pt_cfgwrite
vdev_hostbridge_init
vdev_hostbridge_deinit
vdev_hostbridge_cfgread
vdev_hostbridge_cfgwrite

This is in preparation for removal of the partition modes vdev ops, and call them
directly instead.
