The prior commits create the separate hash so now it is time to update
the initramfs framework so that veritysetup, which is responsible for
binding the data and hash, is aware of when separate hash is in use,
and can react accordingly.
The added code follows the existing appended hash code style, but is
considerably smaller because it doesn't have the large case statement
that supports all possible identification schemes (label, UUID, ...).
With the root hash split in two to create the respective partition
UUIDs, we know exactly how to identify it, and the UUIDs used.

If we use a non PARTUUID root parameter, we would always get a error
like below:
realpath: /dev/disk/by-partuuid//dev/mmcblk0p2: No such file or directory
This seems pretty confusion and it also seems no need to emit this kind
of error when we are waiting for the root device. So suppress all the
realpath errors.

DATA_BLOCK_SIZE variable was set in dm-verity-img.bbclass at build
time but the initrdscript was not updated to pass the DATA_BLOCK_SIZE
to the veritysetup. Now the functionality is complete.

Add 'initramfs-module-dmverity' as an extension to poky upstream
provided initramfs-framework suite via matchingly named bbappend file.
Together with pre-existing 'initramfs-module-udev' this module can be
used to facilitate dm-verity rootfs mounting from initramfs context
that is bundled with Linux kernel.

This adds various bits and pieces to enable generating a working example
of a full chain of trust up to dm-verity-protected rootfs level on Beagle
Bone Black.
The new initramfs is quite generic and should work for other SoCs as well
when using fitImage.
The following config can be used with current master poky,
meta-openembedded & meta-security to generate a BBB image using verified
boot and dm-verity.
