media: hantro: Auto generate the AXI ID to avoid conflicts
The AXI ID is an AXI bus configuration for improve bus performance. If read and write operations use different IDs the operations can be paralleled, whereas when they have the same ID the operations will be serialized. Right now, the write ID is fixed to 0 but we can set it to 0xff to get auto generated IDs to avoid possible conflicts. This change has no functional changes, but seems reasonable to let the hardware to autogenerate the ID instead of hardcoding in software.
