tty/hvc: possible irq lock inversion dependency detected

Hi, Ok, now we have a new locking issue with interrupts which I found on my P8 box. I haven't found where we take the console_lock, only in hvc_remove. BTW, Ben, looks like it's a bug in hvc_remove: we take spin_lock and then semaphore lock. [178327.461954]
