drm/i915/crt: Use intel_hpd_block/unblock() instead of intel_hpd_disable/enable()
intel_hpd_disable/enable() have the same purpose as
intel_hpd_block/unblock(), except that disable/enable will drop any HPD
IRQs which were triggered while the HPD was disabled, while
block/unblock will handle such IRQs after the IRQ handling is unblocked.
Use intel_hpd_block/unblock() for crt as well, by adding a helper to
explicitly clear any pending IRQs before unblocking.
v2:
- Handle encoders without a port assigned to them.
- Rebase on change in intel_hpd_suspend() documentation.
v3:
- Rebase on the suspend/resume -> block/unblock rename change.
- Clear the pending events only after all encoders have unblocked the
HPD handling.
- Clear the short/long port events for all encoders using the given HPD
pin.
v4:
- Rebase on port->hpd_pin tracking. (Ville)
