[Intel-gfx] [PATCH i-g-t] RFC: split PM workarounds into separate lib

[David Weinehall]

Since the defaults for some external power management related settings
prevents us from testing our power management functionality properly,
we have to work around it. Currently this is done from the individual
test cases, but this is sub-optimal.  This patch moves the PM-related
workarounds into a separate library, and adds some code to restore the
previous settings for the SATA link power management while at it.

This patch should be seen as a RFC; there might be other workarounds
for external issues that should be moved into the library, and if those
workarounds aren't related to power management it might be better to
choose a different name for the library.
