This timeout was being ignored in the MSM DP implementation and instead a hardcoded 500 ms timeout was used. Fix it to use the proper timeout. As part of this we move the hardcoded 500 ms number into the AUX transfer function, which isn't given a timeout. The wait in the AUX transfer function will be removed in a future commit.

Specifically if the kernel has the DP AUX character device enabled and userspace accesses "/dev/drm_dp_auxN" directly then the AUX transfer function will be called regardless of whether a DP device is connected. For eDP panels we have a special rule where we wait (with a 5 second timeout) for HPD to go high. This rule was important before all panels drivers were converted to call wait_hpd_asserted() and actually can be removed in a future commit. For external DP devices we never checked for HPD. That means that trying to access the DP AUX character device (AKA `hexdump -C /dev/drm_dp_auxN`) would very, very slowly timeout. Specifically on my system: $ time hexdump -C /dev/drm_dp_aux0 hexdump: /dev/drm_dp_aux0: Connection timed out real 0m8.200s We want access to the drm_dp_auxN character device to fail faster than 8 seconds when no DP cable is plugged in. Let's add a test to make transfers fail right away if a device isn't plugged in. Rather than testing the HPD line directly, we have the dp_display module tell us when AUX transfers should be enabled so we can handle cases where HPD is signaled out of band like with Type C.
