disp: msm: dp: skip waits when processing usb disconnect in sim mode

With real DP over Type-C sinks, DP driver requests access to USB
combo PHY from USB driver. But in DP SIM mode, there is no real
sink and PD management, so the combo PHY is managed by USB driver
and DP driver uses it without actually claiming it. If the USB
cable is unplugged in this scenario, USB driver notifies the
disconnection through an atomic notifier call. It does not expect
the handler to go into sleep, but the disconnect handler inside
DP driver has multiple wait for events and also sleeps to wait for
HW state updates.

This change passes a skip_wait flag to all the disable functions
to complete disconnect processing by skipping all processor sleeps
and event waits.
