disp: msm: dp: fix simulated hpd_irq handling for real monitors



A mode switch on a real monitor can be triggered by forcing the new
mode using debugfs and initiating an hpd_irq. Due to a missing
check for simulator state, the current driver calls the hpd_irq
callback for simulator even for a real monitor. This change adds
this check.
