[OE-core] [meta-oe][PATCH] image_types.bbclass: add optional size to ubi vols

[Tobias Olausson]

Just noticed there is a serious typo that will make this fail in multiubi settings. It worked for my non-multi setup which was just lucky variable naming. Will send an updated patch.

Instead of hard coding the ubi volume to be just large enough to fit the
root file system, one can use a variable to set a preferred size.
