[PATCH v2] drm/amdkfd: Make process queues logs less verbose

[Julian Sax]

During normal usage, especially if jobs are started and stopped in rapid
succession, the kernel log is filled with messages like this:

[38732.522910] Restoring PASID 0x8003 queues
[38732.666767] Evicting PASID 0x8003 queues
[38732.714074] Restoring PASID 0x8003 queues
[38732.815633] Evicting PASID 0x8003 queues
[38732.834961] Restoring PASID 0x8003 queues
[38732.840536] Evicting PASID 0x8003 queues
[38732.869846] Restoring PASID 0x8003 queues
[38732.893655] Evicting PASID 0x8003 queues
[38732.927975] Restoring PASID 0x8003 queues

According to [1], these messages are expected, but they carry little
value for the end user, so turn them into debug messages.
