boards: arm: stm32157c-dk2: fix openocd configuration

Browse source 
By default the port 3333 is assigned for the debug of the
Cortex-A CPUx. the port 3334 is assigned for the Cortex-M debug.

This configuration does not allow to debug the Cortex-M.
More than that the stm32mp157 Cortex-A is not supported in zephyr.

This patch introduces openocd configuration, which
allow to use the Zephyr openocd for the Cortex-M.

The configuration consists in disabling the stm32mp15x.cpu<X> port
to set the stm32mp15x.cm4 port to 3333.
