malta: replace chr init by CHR_EVENT_OPENED handler
The CharDriverState.init() callback was introduced in commit ceecf1d158. It is only called from text_console_do_init(), but it is no longer set since commit a61ae7f88 (init assignment has been removed by accident). It seems correct to use an event callback instead and print the console text on CHR_EVENT_OPENED. That way we can remove the single user of CharDriverState init().
