MAINTAINERS: Add Manivannan Sadhasivam as PCI Endpoint maintainer

The PCI endpoint subsystem is evolving at a rate I cannot keep up with,
therefore I am standing down as a maintainer handing over to Manivannan
(currently reviewer for this code) and Krzysztof who are doing an excellent
job on the matter - they don't need my help any longer.
