tcl/board: Add am62p/am62a7/j722s native swd configuration

Direct memory driver swd native configuration for am62a7, am62p and
J722S SoCs. All three share common memory map for the debug address
map, so there is a strong reuse. However, introduce board file
specific to the board to allow users to directly get started.
