[PATCH v1 07/24] drivers: crypto: meson: move algs definition and cipher API to cipher.c

[Alexey Romanov <avromanov@salutedevices.com>]

From: Jan Dakinevich <yvdakinevich@salutedevices.com>

Because that is proper place for them. In particular,
it takes less of exported symbol between compiling entities.
