Subject: [PATCH] crypto: sha{256,512}_ssse3 - remove asmlinkage from static functions

Commit 128ea04a9885("lto: Make asmlinkage __visible") restricts
asmlinkage to externally_visible, this causes compilation warnings:

    arch/x86/crypto/sha256_ssse3_glue.c:56:1:
    warning: ‘externally_visible’ attribute have effect only on public objects [-Wattributes]

    static asmlinkage void (*sha256_transform_asm)(const char *, u32 *, u64);
    ^

    arch/x86/crypto/sha512_ssse3_glue.c:55:1:
    warning: ‘externally_visible’ attribute have effect only on public objects [-Wattributes]
    static asmlinkage void (*sha512_transform_asm)(const char *, u64 *,
    ^

Drop asmlinkage here to avoid such warnings.
