[PATCH] crypto: arm64/poly1305 - move data to rodata section

[Jia He]

When objtool gains support for ARM in the future, it may encounter issues
disassembling the following data in the .text section: 
> .Lzeros:
> .long   0,0,0,0,0,0,0,0
> .asciz  "Poly1305 for ARMv8, CRYPTOGAMS by \@dot-asm"
> .align  2

Move it to .rodata which is a more appropriate section for read-only data.

Inspired by commit 1253cab8a352, although currently objtool hasn't been
supported on Arm, we should do some preparation(this patch) firstly.
