sparc: Save/restore only non-volatile context
The _CPU_Context_switch() is a normal function call. The following
registers are volatile (the caller must assume that the register
contents are destroyed by the callee) according to "SYSTEM V APPLICATION
BINARY INTERFACE - SPARC Processor Supplement", Third Edition: g1, o0,
o1, o2, o3, o4, o5. Drop these registers from the context.
Ensure that offset defines match the structure offsets.
