This is the new API for allocating DRM bridges.
This driver has a peculiar structure. zynqmp_dpsub.c is the actual driver,
which delegates to a submodule (zynqmp_dp.c) the allocation of a
sub-structure embedding the drm_bridge and its initialization, however it
does not delegate the drm_bridge_add(). Hence, following carefully the code
flow, it is correct to change the allocation function and .funcs assignment
in the submodule, while the drm_bridge_add() is not in that submodule.
