PCI: rockchip-ep: Improve rockchip_pcie_ep_unmap_addr()
There is no need to loop over all regions to find the memory window used
to map an address. We can use rockchip_ob_region() to determine the
region index, together with a check that the address passed as argument
is the address used to create the mapping. Furthermore, the
ob_region_map bitmap should also be checked to ensure that we are not
attempting to unmap an address that is not mapped.
