tcl: target: am437x.cfg: pass correct dbgbase Since commit ec9ccaa28849 (arm_adi_v5: make dap_lookup_cs_component() traverse subtables and handle multicore) AM437x devices can't be used with OpenOCD anymore. The reason is that dbgbase used to be set to zero before that commit and that just happens to work with AM437x devices. A more robust solution is to pass correct dbgbase when creating the target, which this commit does.
