msm: kgsl: Re-enable 64 bit mode after GFT



Fault tolerance recovery does a soft reset so it goes down a similar
but different path then full blown start. Support to enable 64 bit
mode in the GPU is in the normal path but it was forgotten in the
GFT path. SO if a fault recovery happens and somebody else tries to
use a 64 bit address before the next power collapse then IOMMU faults
are likely.
