In this change, static bandwidth-based IPA perf level voting
is added. Three bandwidth 320 MHz, 160 MHz and below are
defined to stand for three bw levels namely High, Medium
and Low. These three levels in turn are translated into
3 perf levels to vote IPA perf levels, which are NOMINAL,
SVS and Low-SVS.

qcacmn: Handle ipa_mapped flag correctly to prevent race

Currently soc->ipa_mapped flag is set to true only after all
the buffers are SMMU mapped to IPA. This leads to a race
window where Rx buffers routed to WLAN HOST in the replenish
path are not mapped to IPA, as the ipa_mapped flag is still
set to 0. The fix is to set the ipa_mapped flag to 1, right when
the IPA pipes are enabled, before waiting for the complete
buffer pool to be IPA SMMU mapped.
With this fix, RX buffers can be unmapped and mapped to IPA
domain in dp_pdev_rx_buffers_attach() and
dp_pdev_nbuf_alloc_and_map_replenish() in WLAN host RX path when
ipa pipes are enabled.

This change also renames ipa_mapped flag to ipa_map_allowed.

qcacmn: Check for target_suspend state before issuing WMI

In OPT_WIFI_DP we perform a system_wakeup before issuing WMI command
to FW to disable low power mode. But as this is not a blocking call,
WMI command could be sent to FW before target is completely
resumed. This will trigger an intentional safety assert.
This change will wait 500ms for target to resume and send

qcacmn: Initialize ipa_mapped to 1 in soc attach

Two SMMU issues are seen on IPA domain with regard to RX.
1. map without unmap
2. Buffers not mapped into IPA.

With If198a6c5f22af58fdaf9d9c020c74b1f76002e37, mapping
RX buffers to IPA domain are deferred to IPA enable pipes
phase with soc->ipa_mapped flag check added. This leads
to a race window where RX packets are routed to WLAN Host
first with soc->ipa_mapped still being 0. In such case, RX
buffers handled by WLAN driver will neither unmap from IPA
domain nor map into IPA domain.

For !ipa_config_is_opt_wifi_dp_enabled(), fix is to set
soc->ipa_mapped to 1 earlier in soc attach phase instead of
IPA enable pipes phase. With this fix, RX buffers can be unmapped
from IPA domain and mapped to IPA domain in dp_pdev_rx_buffers_attach()
and dp_pdev_nbuf_alloc_and_map_replenish() in WLAN host RX path so
as to avoid above two SMMU issues.

With this, WLAN_IPA_RX_PIPE will be equal to 4, leading to array index
out of bounds buffer overflow.

Fix is to set WLAN_IPA_RX_PIPE to WLAN_IPA_MAX_SYSBAM_PIPE - 1 to point
to last index of ipa_ctx->sys_pipe[].

On sdxpinn target (first multi-core MDM platform) with rome

The second AP always goes with sw path because wlan firmware isn't
notified to choose IPA path by wlan_ipa_uc_offload_enable_disable().

SAP are started if MDM_PLATFORM is defined.
