[PATCH 1/5] lib/crypto: arm/poly1305: Remove unneeded empty weak function

[Eric Biggers]

The __weak and empty definition of poly1305_blocks_neon() was a
workaround to prevent link errors when CONFIG_KERNEL_MODE_NEON=n, as
compilers didn't always optimize out the call.

This call is now guarded by IS_ENABLED(CONFIG_KERNEL_MODE_NEON).  That
guarantees the call is removed at compile time when NEON support is
disabled.  Therefore, the workaround is no longer needed.
