For ASICs NAVI10 and above setting display clock [DCEFCLK] is not supported and the sysfs entry is
read-only. As a result, the test falsely fails for these ASICs. ROCm SMI Lib is ASIC independent.
So Display clock set cannot be selectively disabled for these ASICs.
As a compromise if the set (write to sysfs entry) fails due to permission error and euid is root,
assume that set feature is not supported and 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.
