drm/v3d: Increase the autosuspend delay

The downstream implementation of power management for v3d used a 100ms
delay and it has been tested for many years with success. Use the same
delay with the runtime PM implementation.

Although the shorter 50ms delay is not problematic in RPi 5, it can
cause occasional GPU resets on RPi 4 during intensive workloads, due
to the overhead of negotiating with the ASB bridge during frequent
power domain transitions.
