arm64: defconfig: Ensure CRYPTO_CHACHA20_NEON is selected

From: Fabio Estevam <[email protected]>

Since commit 17ec3e71ba79 ("crypto: lib/Kconfig - Hide arch options from user"), the CRYPTO_CHACHA20_NEON option is no longer selected by default due to changes in how crypto library options are exposed and selected.

To restore the previous behavior and ensure CRYPTO_CHACHA20_NEON is enabled, explicitly select CONFIG_CRYPTO_CHACHA20 in the defconfig. This pulls in CRYPTO_LIB_CHACHA_INTERNAL and allows CRYPTO_CHACHA20_NEON to be selected automatically as before.
