Workaround for booting time crash in R-CarH3SK wth Kingfisher board
When I run AGL Instrument Cluster with IVI in R-CarH3SK wth Kingfisher
board, it's frequently crash at booting time.
RGX driver has race condition issue at firmware download time. This issue
occur in multi compositor environment such as IC container integration.
This issue will fix by renesas in next BSP update time, may be.
This patch enable workaround for this race condition issue.
