[Qemu-arm] [PATCH v2] timer/aspeed: fix vmstate version id

[Cédric Le Goater]

commit 1d3e65aa7ac5 ("hw/timer: Add value matching support to
aspeed_timer") increased the vmstate version of aspeed.timer because
the state had changed, but it also bumped the version of the
VMSTATE_STRUCT_ARRAY under the aspeed.timerctrl which did not need to.

Change back this version to fix migration.

 To test on a 'palmetto-bmc' board, download the latest built OpenBMC
 flash image :

   wget 
https://openpower.xyz/job/openbmc-build/distro=ubuntu,target=palmetto/lastSuccessfulBuild/artifact/deploy/images/palmetto/flash-palmetto

 start two instances of QEMU with :

   qemu-system-arm -m 512 -M palmetto-bmc -drive 
file=./flash-palmetto,format=raw,if=mtd -serial mon:stdio -nographic -nodefaults

 and :
 
   qemu-system-arm -m 512 -M palmetto-bmc -drive 
file=./flash-palmetto,format=raw,if=mtd -serial mon:stdio -nographic 
-nodefaults -incoming tcp::1234

 then, run migrate from the monitor:
 
   (qemu) migrate tcp:localhost:1234
