New hardware RNG for Octeon SOCs (v2)

Based on feedback from AKPM, I have a new revision of the Octeon hardware RNG driver.

The changes from v1 are minor, just eliminating some bogus casting by accessing the driver state by embedding struct hwrng in the driver data, which is now accessed with the container_of() trick.

The first patch adds some port definitions and the octeon_rng platform device. The second is the driver.

Since Octeon is a mips port, we might want to merge both patches via Ralf's linux-mips.org tree.

MIPS: Octeon: Add hardware RNG platform device.
hw_random: Add hardware RNG for Octeon SOCs.
