By default, only consider AMD GPU's in RSMI device list

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
