msm: kgsl: Turn back on the SP/TP regulator after a soft reset 



The SP/TP regulator lives inside of the GPU and thus gets reset
along with the rest of the GPU after a soft reset.  Re-enable it
after a soft reset.  While we are at it remove an accidental soft
reset earlier in the sequence that is harmless yet uneeded.
