[SPARC64]: Use 13-bit context size always.

We no longer have the problems that require using the smaller
sizes.

/*
* For the 8k pagesize kernel, use only 10 hw context bits to optimize some
* shifts in the fast tlbmiss handlers, instead of all 13 bits (specifically
* for vpte offset calculation). For other pagesizes, this optimization in
* the tlbhandlers can not be done; but still, all 13 bits can not be used
* because the tlb handlers use "andcc" instruction which sign extends 13
* bit arguments.
