ARM: dts: stm32: add Hardware debug port (HDP) on stm32mp157c-dk2 board

Browse Source 
On the stm32mp157fc-dk2 board, we can observe the hdp GPOVAL function on
SoC pin E13 accessible on the pin 5 on the Arduino connector CN13.
Add the relevant configuration but keep it disabled as it's used for
debug only.
