cmd/internal/obj: remove bogus load/store optab entries from ppc64

Browse source 
No valid operation should match those removed by this patch. They
kind of look as if they match X-form load/stores on ppc64, but the
second argument is always ignored when translating to machine code.

Similarly, it should be noted an X-form memory access encodes into
an Addr which is a classified as a ZOREG argument with a non-zero
index, and a register type Addr.
