This simplifies checking for default resource range for bus_alloc_resource(),
and improves readability.
This is part of, and related to, the migration of rman_res_t from u_long to
uintmax_t.

Some chip revisions don't have their external PCIe buses
behind the internal bridge. Add support for FDT-configurable
PEMs but keep ability for PCIe enumeration.

ofw_bus_get_node() must be tested against negative values since
missing parent bus method will result in calling the default method
which simply returns (-1): sys/dev/ofw/ofw_bus_if.m
This was lost in the review process.

New ThunderX firmware incorporates modified DTB that presents
different device hierarchy. In the new device tree, MDIO
devices are below two additional buses that oddly hang on
PCI bridge.

- Avoid using BUS_ macros as bus_generic_ functions should be used instead.
- Fix mistaken device_t pointers in thunder_pcie_alloc_resource.
Should use dev->parent method and allocate resource for child device

- Drop some irrelevant printfs that cannot be displayed in

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

When one tries to allocate a resource with unspecified range,
read already configured BAR values (by UEFI or whatever).
This is necessary to make VNIC VFs working and to allow them to be
properly allocated.
