Using the newly added fsl_mc_get_endpoint function a fsl-mc driver can
find its associated endpoint (another object at the other link of a MC
firmware link).
The API will be used in the following patch in order to discover the
connected DPMAC object of a DPNI.
Also, the fsl_mc_device_lookup function is made available to the entire
fsl-mc bus driver and not just for the dprc driver.

Starting with v5 of NXP QBMan devices the hardware supports using
regular cacheable/shareable memory as the backing store for the
portals.
This patch adds support for the new portal mode by switching to
use the DPRC get object region v2 command which returns both
a base address and offset for the portal memory. The new portal
region is identified as shareable through the addition of a new
flag.

Allocatable devices can be acquired by drivers on the fsl-mc bus using
the fsl_mc_portal_allocate or fsl_mc_object_allocate functions. Add a
device link between the consumer device and the supplier device so that
proper resource management is achieved.
Also, adding a link between these devices ensures that a proper unbind
order is respected (ie before the supplier device is unbound from its
respective driver all consumer devices will be notified and unbound
first).
