Matt Brown e66ca3db59 powerpc/powernv: Use darn instruction for get_random_seed() on Power9 ... This adds powernv_get_random_darn() which utilises the darn instruction, introduced in ISA v3.0/POWER9. The darn instruction can potentially return an error, which is supported by the get_random_seed() API, in normal usage if we see an error we just return that to the caller. However when detecting whether darn is functional at boot we try up to 10 times, before deciding that darn doesn't work and failing the registration of get_random_seed(). That way an intermittent failure at boot doesn't deprive the system of randomness until the next reboot.
