aes: make apply_cbc_chain_data non-static
Tegra's crypto.c uses apply_cbc_chain_data() to sign the warm restart
code. This function was recently moved into the core aes.c and made
static, which prevents the Tegra code from compiling. Make it public
again to avoid the compile errors:
arch/arm/cpu/tegra20-common/crypto.c: In function ‘sign_object’:
arch/arm/cpu/tegra20-common/crypto.c:74:3: warning: implicit declaration of function ‘apply_cbc_chain_data’ [-Wimplicit-function-declaration]
arch/arm/cpu/built-in.o: In function `sign_object':
.../arch/arm/cpu/tegra20-common/crypto.c:74: undefined reference to `apply_cbc_chain_data'
.../arch/arm/cpu/tegra20-common/crypto.c:78: undefined reference to `apply_cbc_chain_data'
Fixes: 6e7b9f4fa0ae ("aes: Move the AES-128-CBC encryption function to common code")
