sparc64: Make global reg dumping even more useful.

[ Upstream commit 5afe27380bc42454254c9c83c045240249c15e35 ]

Record one more level of stack frame program counter.

Particularly when lockdep and all sorts of spinlock debugging is
enabled, figuring out the caller of spin_lock() is difficult when the
cpu is stuck on the lock.
