[PATCH 2/2] mips: dts: ralink: mt7621: add crypto offload support

[Aleksander Jan Bajkowski]

Add support for the built-in cryptographic accelerator. This accelerator
supports 3DES, AES (128/192/256 bit), ARC4, MD5, SHA1, SHA224, and SHA256.
It also supports full IPSEC and TLS offload, but this feature isn't
implemented in the driver.
