PCI/DOE: Make asynchronous API private

A synchronous API for DOE has just been introduced.  CXL (the only
in-tree DOE user so far) was converted to use it instead of the
asynchronous API.

Consequently, pci_doe_submit_task() as well as the pci_doe_task struct
are only used internally, so make them private.

- *
- *	1) The request_pl_sz must be a multiple of double words (4 bytes)

- *	3) rv is returned as bytes but it will be a multiple of double words
- *
- * NOTE there is no need for the caller to initialize work or doe_mb.
