Pull random number generator fixes from Jason Donenfeld:

 - If a hardware random number generator passes a sufficiently large
   chunk of entropy to random.c during early boot, we now skip the
   "fast_init" business and let it initialize the RNG.

   This makes CONFIG_RANDOM_TRUST_BOOTLOADER=y actually useful.

 - We already have the command line `random.trust_cpu=0/1` option for
   RDRAND, which let distros enable CONFIG_RANDOM_TRUST_CPU=y while
   placating concerns of more paranoid users.

   Now we add `random.trust_bootloader=0/1` so that distros can
   similarly enable CONFIG_RANDOM_TRUST_BOOTLOADER=y.

 - Re-add a comment that got removed by accident in the recent revert.

 - Add the spec-compliant ACPI CID for vmgenid, which Microsoft added to
   the vmgenid spec at Ard's request during earlier review.

 - Restore build-time randomness via the latent entropy plugin, which
   was lost when we transitioned to using a hash function.
