target/arm_dap: clean up dap_configure code 

dap_configure() contained first time init related tasks, as the call to
dap_init_instance() and the check for configured tap.

Move all first time init related stuff to dap_create() to make dap_configure()
usable in eventual stand-alone 'dap configure' command.
