The aspeed video (be compatible for ast2400, ast2500, ast2600) now needs
the reset DTS handle specified, otherwise it will fail to load:
[ 4.809494] aspeed-video 1e700000.video: irq 57
[ 4.809977] aspeed-video 1e700000.video: Unable to get reset
[ 4.810341] aspeed-video 1e700000.video: probe with driver aspeed-video failed with error -2
Fixes: e83f8dd668ea ("media: aspeed: Fix dram hang at res-change")
