crypto: powerpc - Use address generation helper for asm
Replace open-coded toc-relative address calculation with helper macros,
commit dab3b8f4fd09 ("powerpc/64: asm use consistent global variable
declaration and access") made similar conversions already but missed
this one.
This allows data addressing model to be changed more easily.
