[PATCH v1] media: aspeed: Fix driver probe failure

[Haiyue Wang]

The aspeed video (be compatible for ast2400, ast2500, ast2600) now needs
the reset DTS handle specified, otherwise it will fail to load:

[    0.000000] OF: reserved mem: initialized node video, compatible id shared-dma-pool
[    0.000000] OF: reserved mem: 0xbb000000..0xbeffffff (65536 KiB) map reusable video
[    0.377039] videodev: Linux video capture interface: v2.00
[    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")
