ARM: dts: dra72-evm: Add CAN support
The board has 2 CAN ports but only the first one can be used. Enable the first CAN port. WAKEUP0 pin doesn't have INPUT enable bit so we just disable weak PULLs. The second CAN port cannot be used without hardware modification so we don't enable the second port. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
