phy: Move phy code in dev/phy

We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory
at first, we now have a lot of consumer of it and we made it mandatory
so no need to have it under a cryptic name.

Map arm64 pci config memory as non-posted

On arm64 PCI config memory is expected to be mapped with a non-posted
device type. To handle this use the new bus_map_resource support in
arm64 to map memory with the new VM_MEMATTR_DEVICE_NP attribute. This
memory has already been allocated and activated, it just needs to be
mapped.

Rename ofwpci.c to ofw_pcib.c

It's a class0 driver that implements some pcib methods and creates
a pci bus as its children.
The "ofw_pci" name will be used by a new driver that will be a subclass
of the pci bus.
No functional changes intended.

Convert extres/phy to kobj model.
Similarly as other extres pseudo-drivers, implement phy by using kobj model.
This detaches it from provider device, so single device driver can export
multiple different phys. Additionally, this allows phy to be subclassed to
more specialized drivers, like is USB OTG phy, or PCIe phy with hot-plug
capability.
