When we didn't find a device and didn't guess it might be a partition,
it might still show up later, so don't disable rootwait for it by
returning -EINVAL.

Fix the documentation of the devt_from_partuuid() return value.
Fix the following two recently introduced kernel-doc warnings:

block/early-lookup.c:46: warning: Function parameter or member 'devt' not described in 'devt_from_partuuid'

The previous rootwait fix added an -EINVAL return to a completely
bogus superflous branch, fix this.

Failures to look up the gendisk must return -ENODEV so that rootwait
retries the lookup instead of -EINVAL which exits early.

early_lookup_bdev is now only used during the early boot code as it
should, so mark it __init to not waste run time memory on it.

blk_lookup_devt is only used by code in early-lookup.c, so move it
there.
printk_all_partitions and it's helper bdevt_str are only used by the
early init code in init/do_mounts.c, so they should go there as well.

Create a new block/early-lookup.c to keep the early block device lookup
code instead of having this code sit with the early mount code.
