IOMMU path in sysfs was amd_iommu. After implementing multiple devices
support, the path is replaced with amd_iommu_<index>. Current Thunk spec
is not clear about how to support multiple instances in one block. There
is no products having multiple IOMMUs yet at this point. This patch
changes the path to support both amd_iommu and amd_iommu_0 for Carizo.

Libraries normally don't print messages. We use pr_err, pr_warn,
pr_info, and pr_debug to print messages to stderr when prints are
enabled for debugging.

Use checkpatch.pl to fix the majority of errors. Some that remain and
will be excluded:
Use of typedefs/externs/volatile/sscanf
Lines over 80 characters
Remaining errors are due to misunderstanding the * symbol with typedefs
Also use this opportunity to spell manageable properly

This patch adds more non-privileged PMC blocks to GFX9/gfx900 to cover
blocks added in HSA Thunk Spec.

This patch adds more non-privileged PMC blocks to GFX8 products: gfx801,
gfx803, and gfx803. Most of them have the same counter IDs on the same
block. For certain blocks when the product doesn't have the same counter
IDs, gfx8_xx_ is used to represent the product.

HSA Thunk Spec was updated to include more non-privileged blocks for
profiling. This patch adds those newly added non-privileged blocks for
gfx70x.

Many devices have the same counter IDs for the hardware block. Devices
in the same GFX generation usually have the same block counters. No need
to list each device individually. Instead, have a table to share with all
devices that have the same counter IDs, and have separated tables for
devices that don't have the same counter IDs.

Integrate the supported device ID list distributed in topology, queue, and
pmc into one place: topology.

Existing code uses lockf to ensure exclusive PMC access of one process and
one TraceId. However Thunk spec allows hsaKmtPmcAcquireTraceAccess to get
exclusive access to the defined set of counters, not exclusive to one
process or one TraceId. Multiple counter sets of multiple TraceIds is
allowed if they meet the concurrent access limit evaluated by the hardware
/driver.

Add IOMMUv2 to blocks returned by hsaKmtPmcGetCounterProperties(). IOMMU
information is read from sysfs.

Thunk follows Linux kernel coding convention to use tabs instead of
spaces.

get_block_properties uses the complete DID to identify the GPU. This list
is getting too long when more devices are added. Reading the 12 most
significant digits is good enough to identify the GPU.

Add performance counters for gfx70x. The reference is the gfx7 register spec.
The register being looked at is SQ_PERFCOUNTER0_SELECT.
Change-Id: I344bfb7452f6148f4dc268163d12c553c6be8424
Few more counters are now available in GFX8 register specs. So adding
them. Also for gfx700 and gfx801 report correct number of SQ perf counter slots
