Sebastian Reichel 14adddc653 drm/bridge: dw-hdmi-qp: Fix spurious IRQ on resume
After resume from suspend to RAM, the following splash is generated if
the HDMI driver is probed (independent of a connected cable):

[ 1194.484052] irq 80: nobody cared (try booting with the "irqpoll" option)
[ 1194.484074] CPU: 0 UID: 0 PID: 627 Comm: rtcwake Not tainted 6.17.0-rc7-g96f1a11414b3 #1 PREEMPT
[ 1194.484082] Hardware name: Rockchip RK3576 EVB V10 Board (DT)
[ 1194.484085] Call trace:
[ 1194.484087]  ... (stripped)
[ 1194.484283] handlers:
[ 1194.484285] [<00000000bc363dcb>] dw_hdmi_qp_main_hardirq [dw_hdmi_qp]
[ 1194.484302] Disabling IRQ #80

Apparently the HDMI IP is losing part of its state while the system
is suspended and generates spurious interrupts during resume. The
bug has not yet been noticed, as system suspend does not yet work
properly on upstream kernel with either the Rockchip RK3588 or RK3576
platform.
