[PATCH] crypto: arm/sha512 - make function static

[Philippe Mazenauer]

Function sha512_arm_final() is only used in this file, therefore should
be static

../arch/arm/crypto/sha512-glue.c:40:5: warning: no previous prototype for âsha512_arm_finalâ [-Wmissing-prototypes]
 int sha512_arm_final(struct shash_desc *desc, u8 *out)
     ^~~~~~~~~~~~~~~~
