Subject: [PATCH] ec: Use static linkage on nistp521 felem_{square,mul}
wrappers
Runtime selection of implementations for felem_{square,mul} depends on
felem_{square,mul}_wrapper functions, which overwrite function points in
a similar design to that of .plt.got sections used by program loaders
during dynamic linking.
There's no reason why these functions need to have external linkage.
Mark static.

Add an assembly implementation of felem_{square,mul}, which will be
implemented whenever Altivec support is present and the core implements
ISA 3.0 (Power 9) or greater.

Subject: [PATCH] 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}().
