Subject: [PATCH] platform/x86/amd/hsmp: switch to use device_add_groups()

The use of devm_*() functions works properly for when the device
structure itself is dynamic, but the hsmp driver is attempting to have a
local, static, struct device and then calls devm_() functions attaching
memory to the device that will never be freed.

The logic of having a static struct device is almost never a wise
choice, but for now, just remove the use of devm_device_add_groups() in
this driver as it obviously is not needed.
