wifi: ath12k: add multi device support for WBM idle ring buffer setup

Browse source

Currently, inter device MLO is not supported. Therefore, the WBM idle ring
buffers choose the implicit return buffer manager (DEV0_IDLE_DESC_LIST).
However, this implicit return buffer manager design is not meeting the
requirements to support inter device MLO. In inter device MLO, multiple
devices participate. The device specific WBM idle ring buffers transmit
to multiple device REO rings. To distinguish between device specific WBM
idle buffers, the setup configuration need to choose a different return
buffer manager based on the unique identifier (device index).
