Update the existing overlay which configures PCIE0 instance of PCIe on
J721E-EVM in Endpoint mode of operation, in order to configure PCIE1
instance of PCIe as well in Endpoint mode of operation. Hence, change the
name of the overlay to reflect its updated functionality.
What if I only want PCIe0 to be in EP mode? Why not make a separate
DTBO for PCIe1, that way I can have one in EP and the other in RC,
and mix and match as needed.
