DOE mailbox objects will be needed for various mailbox communications
with each memory device.

Iterate each DOE mailbox capability and create PCI DOE mailbox objects
as found.

It is not anticipated that this is the final resting place for the
iteration of the DOE devices.  The support of switch ports will drive
this code into the PCIe side.  In this imagined architecture the CXL
port driver would then query into the PCI device for the DOE mailbox
array.

For now creating the mailboxes in the CXL port is good enough for the
endpoints.  Later PCIe ports will need to support this to support switch
ports more generically.

Introduced in a PCIe r6.0, sec 6.30, DOE provides a config space based
mailbox with standard protocol discovery.  Each mailbox is accessed
through a DOE Extended Capability.

Each DOE mailbox must support the DOE discovery protocol in addition to
any number of additional protocols.

Define core PCIe functionality to manage a single PCIe DOE mailbox at a
defined config space offset.  Functionality includes iterating,
creating, query of supported protocol, and task submission.  Destruction
of the mailboxes is device managed.

bound to it. In event of failing the bind (e.g. failure in cxl_port_probe())
the device is left registered. When a bus rescan later occurs, fresh
devices are created leading to a multiple device representing the same
underlying hardware. Bad things may follow and at very least we have far too many
devices.

Fix by ensuring autoremove is registered if the device create succeeds,
but doesn't depend on sucessful binding to a driver.
