6d90ef32d5 qcacmn: Separate peer object creation from other initialization
Seperate the dp peer object allocation from setting the peer's
default routing and default rx tid queues.

This change is to address a race condition where the HTT peer map
message arrives before the peer object is created.

7351d17b41 qcacmn: MCL Buffer Replenishment
Add support for replenishing the rx buffers using the host to
firmware buffer ring.

This includes adding a flag QCA_HOST2FW_RXBUF_RING:
When QCA_HOST2FW_RXBUF_RING is enabled the host will do the following:
- Allocate the refill buffer ring (HTT_HOST1_TO_FW_RXBUF_RING) and
populate it with
 rx buffers
- Send the refill buffer ring configuration to the firmware
- Allocate the rx DMA ring (HTT_RXDMA_HOST_BUF_RING), leave it empty.
- Send the rx DMA ring configuration to the firmware

When QCA_HOST2FW_RXBUF_RING is disabled, the host will do the following:
- Allocate the rx DMA ring (HTT_RXDMA_HOST_BUF_RING), and populate it with
 rx buffers
- Send the rx DMA ring configuration to the firmware
