Currently the dp_display_request_irq() is executed at msm_dp_modeset_init()
which ties irq registering to the DPU device's life cycle, while depending on
resources that are released as the DP device is torn down. Move register DP
driver irq handler to dp_display_probe() to have dp_display_irq_handler()
IRQ tied with DP device. In addition, use platform_get_irq() to retrieve irq
number from platform device directly.

Changes in v5:
-- reworded commit text as review comments at change #4
-- tear down component if failed at dp_display_request_irq()

Changes in v4:
-- delete dp->irq check at dp_display_request_irq()

Changes in v3:
-- move calling dp_display_irq_handler() to probe
