Increase default size of UBI read-write volume
The default size of the UBI read-write volume is currently set to 4MB.
There are no plans to store more than one BMC rootfs image on the chip
so in a 32MB flash chip, accounting for the current rootfs image size
of ~15MB with plans to grow to ~20MB with the addition of redfish and
other packages, it is safe to increase the read-write volume size to
6MB since the current size is already almost completely taken up if
there are multiple error logs / dumps on the system.
In addition, make the size configurable from a recipe so that the
size can be changed in a per-system basis. And during code update,
check the current size and update it if it's different, this allows
systems to be able to be resized to a new size by performing factory
reset after a code update that sets the new size.
Tested:
- Booted on QEMU and verified non-ubi system (romulus) retains the
current 4MB read-write volume, and ubi system (witherspoon) has a
6MB volume.
- Code updated to an image that has these changes and verified the
rwfs_size env variable changes to 6MB, and that a subsequent factory
reset rebuilds the volume with size 6MB.
