Given a process ID, give the device indices that process is
currently using.
Also:
* made corrections to how RSMI, amdgpu (ie, "card#") and
KFD indicies translate from one another
* add a few missing error codes to rsmi_status_string()
* fix some formatting
Change-Id: Icd2cae66bb4fec768da96af7cf9cf8b8b66ec7f9
* Update doc. on api-support function
* Check for valid integer value when reading a monitor int. val.
* If fan-write test attempts to set speed higher than max.
possible, then skip the test

For device-getter functions, allow users to specify a nullptr
for the provided buffer. In those cases, the function will return
RSMI_STATUS_NOT_SUPPORTED if the hardware or system software does
not support the function. If the function is supported, then
RSMI_STATUS_INVALID_ARGS will be returned, unless a different
error is encountered.
Additionally, tests and documentation were updated to reflect
this change.

Add support and testing for reading the vram vendor associated with
the GPU. The vram vendor can be found as a separate sysfs file at:
/sys/class/drm/card[X]/device/mem_info_vram_vendor
The vram vendor is displayed as a string value.

The new functions added in this commit allow a caller to tell up
front what functions, function variants and monitors are
supported.
Also,
* fixed a few documentation/formatting issues
* fixed a process_info test issue

Add support and testing for reading the brand name associated with
a specific GPU (such as mi25, mi50, mi60, etc). The brand name is
associated with the SKU of the GPU, and some brand names can be
mapped from multiple different SKUs.

Also, don't return an error for empty sysfs files. The reserved memory
page file will often have no lines. We don't want it to appear that
this function is not supported if the file is empty.

Added implementation of and tests for
rsmi_dev_compute_process_info_by_pid_get() and
rsmi_dev_compute_process_info_get()

Add support and testing for reading the Unique ID associated with a
specific GPU. This ID will persist across reboots, even if the GPU is
moved to a different machine. Note that this is per-GPU, not per-card,
as some cards have multiple GPUs, and each GPU will get a unique
identifier

* If vendor/device/subsystem name is not found, use device ID string
* Update documentation for get-name functions
* Add support for junction, edge and memory temperature sensors
With newly added initialization parameters that can be
passed to rsmi_init(), you can tell RSMI to consider other
devices.
Also:
-fixed incorrect header file name that would break in C
builds
-modified rsmi_init() and rsmi_shut_down() to reinitialize and
clear static structures
In some cases, the fan sysfs files will exist even if the device
doesn't have a fan. In these cases, the tests will give apparently
random results.
Also, remove documentation and ifdef'd test of debugfs related
power functions.
