wifi: ath12k: refactor rx descriptor CMEM configuration
Currently, data path Rx descriptor placed in the CMEM memory respective
to the Rx offset. This Rx descriptor CMEM placement is not meeting the
requirements to support inter device MLO. In inter device MLO, multiple
devices participate in a group. The device specific Rx descriptor buffers
transmit to multiple device REO rings. To distinguish between device
specific Rx descriptor buffers, the CMEM setup configuration need to
choose a different placement based on the unique identifier (device index).
Below are the CMEM configuration placement representation:
Intra-Device MLO scenario:
Device 0 Device 1
+-------------+ +-------------+
| | | |
| Tx | | Tx |
| | | |
+-------------+ +-------------+
| | | |
| Rx | | Rx |

+-------------+ +-------------+
Inter-Device MLO scenario:
Device 0 Device 1
+-------------+ +-------------+
| | | |
| Tx | | Tx |
| | | |
+-------------+ +-------------+
| | | |
| Rx | | Reserved |
| Device 0 | | |
| | | |
+-------------+ +-------------+
| | | Rx |
| Reserved | | Device 1 |
