arm64: Introduce cpu_parange_encoded
Keep the encode parange value as well. This allows to use it directly in
VTCR_CELL, rather than re-encoding it via TCR_PS_CELL. It will also
allow reuse by the SMMUv2 code.

arm64: smmu: Refactor smmu device setup and usage
We only need iommu_units from the system configuration during setup.
Afterwards, we work solely against entries of smmu_device.
Rework the usage of the latter by filling the smmu_device array
independently of the iommu_units and iterating over the former later on.
Introduce an iterator macro for this. Helps to simplify the code.

arm64: smmu: Do not stall failing context transaction
We do not handle faults, e.g. by resuming them later on. Stalling
failed transactions will soon lead to a stalled SMMU, blocking even
valid transactions.
This could easily be reproduced by stealing a used StreamID from the
root cell. On the Zynqmp, this lead to all transactions of the root cell
to be blocked.

arm64: smmu: Refactor S2CR handling
There is no need to cache the value we write to S2CRn. Drop the related
data structure and pass the values to be written to arm_smmu_write_s2cr
directly. This implies dropping arm_smmu_write_sme, open-coding it.
Still a net gain as a lot of boilerplate code can be dropped.
Along this cleanup, convert arm_smmu_s2cr_type and arm_smmu_s2cr_privcfg
into defines, only encoding what we use. There is no value in enums.

arm64: smmu: Check IAS and OAS against CPU parange
Make sure that supported range of the SMMU is compatible with what we
need to use via the MMU settings. Bail out if not, and rather drop
useless reporting in the code case.

arm64: smmu: Demand version 2
We only support version 2, and this should be checked during probe
already. Makes arm_smmu_device_reset a bit simpler.

arm64: smmu: Drop more unused fields from arm_smmu_device
num_s2_context_banks is only locally used during probe, and the rest is
just dead leftover from the Linux driver.

arm64: smmu: Stop caching context bank states
Refactor arm_smmu_init_context_bank/write_context_bank to a unified
setup_context_bank that generates the required register values directly,
without the pointless indirection over arm_smmu_cb and arm_smmu_cfg.
This massively simplifies the code and improves readability.

It still contained fragments of the Linux back-off mechanism which was
removed already. Adjust the loop counters to the new iteration count.
Will wait at least one second now.
