Rename existing HCA capability relaxed_ordering_read to
relaxed_ordering_read_pci_enabled. This is in accordance with recent PRM
change to better describe the capability, as it's set only if both the
device supports relaxed ordering (RO) read and RO is enabled in PCI
config space.

In addition, add new HCA capability relaxed_ordering_read which is set
if the device supports RO read, regardless of RO in PCI config space.
This will be used in the following patch to allow RO in VFs and VMs.
