PCI: endpoint: test: Use pci_epc_mem_map/unmap()

Browse source

Modify the endpoint test driver to use the functions pci_epc_mem_map()
and pci_epc_mem_unmap() for the read, write and copy tests. For each
test case, the transfer (dma or mmio) are executed in a loop to ensure
that potentially partial mappings returned by pci_epc_mem_map() are
correctly handled.
