drm/imagination: Wait for FW trace update command completion

Browse source

[ Upstream commit 812062e74a ]

Possibility of no FW trace available after update in the fw_trace_mask due
to asynchronous mode of command consumption in the FW.

To ensure FW trace is available after update, wait for FW trace log update
command completion from the FW.
