[PATCH v5 7/7] dts: ti: k3-am625-beagleplay: Add mikroBUS

[Ayush Singh <ayush@beagleboard.org>]

DONOTMERGE

Add mikroBUS connector and some mikroBUS boards support for Beagleplay.
The mikroBUS boards node should probably be moved to a more appropriate
location but I am not quite sure where it should go since it is not
dependent on specific arch.
