board: ti: am62px: rm-cfg: Add support for HC BCDMA

The first 4 block copy channels and rings on AM62P support
High Capacity Block Copy. These channels have approximately
3x improvement over the normal Block copy channels when doing
DDR-to-DDR copy.

Currently, during allocation these channels do not have a
separate interface and are allocated with normal BCDMA channels.

Latest TIFS and DM firmware adds support for differentiating these
High Capcity resources. This update is for allocating these new
resource type to different hosts with below mentioned scheme.
