iommu/arm-smmu-v3: Reorganize struct arm_smmu_ctx_desc_cfg

The members here are being used for both the linear and the 2 level case,
with the meaning of each item slightly different in the two cases.

Split it into a clean union where both cases have their own struct with
their own logical names and correct types.

Adjust all the users to detect linear/2lvl and use the right sub structure
and types consistently.

Remove CTXDESC_CD_DWORDS by changing the last places to use
sizeof(struct arm_smmu_cd).
