[Qemu-block] [PATCH-for-4.1 v7 0/1] hw/block/pflash_cfi01: Add DeviceRes

The pflash device lacks a reset() function.
When a machine is resetted, the flash might be in an
inconsistent state, leading to unexpected behavior.
Resolve this issue by adding a DeviceReset() handler.

v7: Surgical bugfix, do not attempt to improve the model in any
    way, thus ignoring all comments from previous versions.
    No migration impact.

Usual regression testing is welcomed, but probably pointless,
except done in the way describes in the following bug reports:
That is, resetting the machine when it is accessing the flash
device. IMO testing after the guest is done accessing the flash
device is totally pointless.

If no objection on this series after a day, I plan to send a
pull request to get this bugfix into 4.1.0-rc2.
