powerpc: ecc: Fix stack allocation secp384r1 asm
Assembly acceleration secp384r1 opts to not use any callee-save VSRs, as
VSX enabled systems make extensive use of renaming, and so writebacks in
felem_{mul,square}() can be reordered for best cache effects.
Remove stack allocations. This in turn fixes unmatched push/pops in
felem_{mul,square}().
