platform/x86/amd: pmc: Always write to the STB
The kernel parameter `enable_stb` currently gates the access to the STB
from debugfs and also controls whether the kernel writes events to the
STB.
Even if not accessing STB data from the kernel it's useful to have this
data stored to review the STB. So in suspend/resume always write it.
