iommu/arm-smmu: Optimize ->tlb_flush_walk() for qcom implementation

Currently for iommu_unmap() of large scatter-gather list with page size
elements, the majority of time is spent in flushing of partial walks in
__arm_lpae_unmap() which is a VA based TLB invalidation invalidating
page-by-page on iommus like arm-smmu-v2 (TLBIVA).

For example: to unmap a 32MB scatter-gather list with page size elements
(8192 entries), there are 16->2MB buffer unmaps based on the pgsize (2MB
for 4K granule) and each of 2MB will further result in 512 TLBIVAs (2MB/4K)
resulting in a total of 8192 TLBIVAs (512*16) for 16->2MB causing a huge
overhead.

On qcom implementation, there are several performance improvements for
TLB cache invalidations in HW like wait-for-safe (for realtime clients
such as camera and display) and few others to allow for cache
lookups/updates when TLBI is in progress for the same context bank.
So the cost of over-invalidation is less compared to the unmap latency
on several usecases like camera which deals with large buffers. So,
ASID based TLB invalidations (TLBIASID) can be used to invalidate the
entire context for partial walk flush thereby improving the unmap
latency.

For this example of 32MB scatter-gather list unmap, this change results
in just 16 ASID based TLB invalidations (TLBIASIDs) as opposed to 8192
TLBIVAs thereby increasing the performance of unmaps drastically.

Test on QTI SM8150 SoC for 10 iterations of iommu_{map_sg}/unmap:
(average over 10 iterations)

Before this optimization:

size iommu_map_sg iommu_unmap
4K 2.067 us 1.854 us
64K 9.598 us 8.802 us
1M 148.890 us 130.718 us
2M 305.864 us 67.291 us
12M 1793.604 us 390.838 us
16M 2386.848 us 518.187 us
24M 3563.296 us 775.989 us
32M 4747.171 us 1033.364 us

After this optimization:

size iommu_map_sg iommu_unmap
4K 1.723 us 1.765 us
64K 9.880 us 8.869 us
1M 155.364 us 135.223 us
2M 303.906 us 5.385 us
12M 1786.557 us 21.250 us
16M 2391.890 us 27.437 us
24M 3570.895 us 39.937 us
32M 4755.234 us 51.797 us

Real world data also shows big difference in unmap performance as below:

There were reports of camera frame drops because of high overhead in
iommu unmap without this optimization because of frequent unmaps issued
by camera of about 100MB/s taking more than 100ms thereby causing frame
drops.

Adreno(GPU) SMMU and APSS(Application Processor SubSystem) SMMU
both implement "arm,mmu-500" in some QTI SoCs and to run through
adreno smmu specific implementation such as enabling split pagetables
support, we need to match the "qcom,adreno-smmu" compatible first
before apss smmu or else we will be running apps smmu implementation
for adreno smmu and the additional features for adreno smmu is never
set. For ex: we have "qcom,sc7280-smmu-500" compatible for both apps
and adreno smmu implementing "arm,mmu-500", so the adreno smmu
implementation is never reached because the current sequence checks
for apps smmu compatible(qcom,sc7280-smmu-500) first and runs that
specific impl and we never reach adreno smmu specific implementation.

iommu/arm-smmu-qcom: Skip the TTBR1 quirk for db820c.

db820c wants to use the qcom smmu path to get HUPCF set (which keeps
the GPU from wedging and then sometimes wedging the kernel after a
page fault), but it doesn't have separate pagetables support yet in
drm/msm so we can't go all the way to the TTBR1 path.

iommu/arm-smmu-qcom: hook up qcom_smmu_impl for ACPI boot

The hookup with qcom_smmu_impl is required to do ACPI boot on SC8180X
based devices like Lenovo Flex 5G laptop and Microsoft Surface Pro X.

iommu/arm-smmu-qcom: hook up qcom_smmu_impl for ACPI boot

The hookup with qcom_smmu_impl is required to do ACPI boot on SC8180X
based devices like Lenovo Flex 5G laptop and Microsoft Surface Pro X.
Define acpi_platform_list for these platforms and match them using
acpi_match_platform_list() call, and create qcom_smmu_impl accordingly.

(np == NULL) is used to check ACPI boot, because fwnode of SMMU device
is a static allocation and thus helpers like has_acpi_companion() don't
work here.
