db845c: make build pg_agnostic and support 16k page size kernels

To support booting with 16k page size kernels, add a new 16k page size
option. This also uses 16k block size for the filesystems in use.

Also add page agnostic support so that 4k and 16k page size kernels
can be booted with 16K aligned userspace.
