Commit Message

J721E has a Flash SubSystem that has one OSPI and one HyperBus with
muxed datapath and another independent OSPI. Add DT nodes for HyperBus
controller and keep it disabled and model the data path selection mux as a
reg-mux.

Signed-off-by: Vaishnav Achath <vaishnav.a@ti.com>

V1->V2:
 * Drop register region size update as the memory maps mentions
 256 Bytes for these regions.
 * Drop FSS node rename as the fix is already present in next.

Depends on :
