Subject: [PATCH v2 0/3] Add support to handle targets without TrustZone

The iommu mapping for S2 SIDs are taken care by TrustZone.
For the targets which does not have the support of TrustZone,
these mappings need to be created in the driver using an
iommu domain.

Leaving these SIDs unconfigured will result in a global
smmu fault. Hence configuring them for Non-TrustZone targets
is mandatory.

Changes from v1:
- Rebase and fix compilation errors on latest ath10k tree tip

  dt-bindings: ath10k: Add wifi-firmware subnode for wifi node
  ath10k: Setup the msa resources before qmi init
  ath10k: Add support for targets without trustzone
