Andreas Färber b7e516ce04 Kill off cpu_state_reset()
In commit 1bba0dc932 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.

All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

Load, store, and "create destination".  This version attempts to

previously used cpu_tmp32 as the temporary destination, and we
continue to use that.  This will eventually allow a change in
representation of the fprs.

Change the name of the cpu_fpr array to make certain that all
