Add properties to enable PCIe x2 lane mode since all dra7
based SoCs support x2 lane mode.

However only dra76-evm has a slot which can support x2 lane
cards. Hence only enable x2 lane mode in dra76-evm.
(am571x-idk can support x2 lane mode but that makes usb port
not functional so not including the patch to enable
x2 mode in am571x-idk)

Also included in this series is patch to enable PCIe configs
(both host and device) in omap2plus_defconfig and
multi_v7_defconfig

In order to get x2 mode working [1] is required.

However by keeping the older compatible, this series won't
break functionality if this series is merged before [1]
