PCI/DOE: Add DOE mailbox support functions
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.
