Imre Deak ae48434c2a drm/i915: vlv: reserve the GT power context only once during driver init 
Atm we reserve/allocate and free the power context during GT power
enable/disable time. There is no need to do this, we can reserve/allocate
the buffer once during driver loading and free it during driver cleanup.
The re-reservation can also fail in case the driver previously manages to
allocate something on the given fixed address.

The buffer isn't exepected to move even if allocated by the BIOS, for
safety add an assert to check this assumption.

This also fixed a bug for Ville, where re-reserving the context failed
during a GPU reset (I assume because something else got allocated on its
fixed address).
