Add apis to map generic registers to shadow region. Existing
logic includes mapping only srng based regs to the shadow
region.
Add support to map REO control regs and WBM2SW2 rel
ring HP reg address to the shadow region in case the direct
reg writes in IPA enable/disable autonomy fail due to UMAC
block being in a power collapsed state.
Shadow reg mapping for these regs is provided to FW during
init. Add stat shadow_reg_write_fail to track shadow reg
write failure and shadow_reg_write_succ to track successful
shadow writes.

In monitor mode, if channel is initially configured from 5G
band and then moved to channel from 2G band, packets are still
received on MAC-0 RXDMA2SW ring since IMPS is disabled for both
MACs. Since driver reaps only MAC-1 RXDMA2SW ring, ring full
condition is hit for the MAC-0 ring causing ring backpressure.
Fix is to drop packets received on the non-monitoring MAC
ring.

For HTT h2t message which has a response from FW, runtime
get is done in HTC layer and the corresponding runtime_put
is done as part of the HTT response processing. In a scenario
where the HTT response is not received from FW or not processed
by host, runtime_put is not done as part of cleanup and panic
is triggered due to get/put imbalance.
Fix is to do RTPM put as part of htc cleanup when the HTT
response from FW is not received or processed.

Skbs allocated for CE1 ring are of size 2048 bytes. On
receiving PPDU stats HTT message, skb is pulled for 8
bytes corresponding to the HTC header length. As part of
dp_ppdu_stats_ind_handler, skb len is set to HTT_MAX_MSG_SIZE.
In the case where skb allocation is exactly of 2048 bytes,
including HTC header length, the aforementioned set_len
causes the skb to be expanded due to lack of tailroom.
This causes the skb data pointer to be changed which results
in invalid memory access.
Fix is to remove the qdf_nbuf_set_pktlen as skb len is
appropriately set by HTC layer.
