meta-yocto-bsp: bump reference BSPs to v3.10.11

Bumping to the 3.10.11 -stable release. Of note in this update is
the timer_list fix, which broke ssh access in the previous 3.10
series of updates:

    timer_list: correct the iterator for timer_list

    commit 84a78a6504f5c5394a8e558702e5b54131f01d14 upstream.

With this, we can revert the two temporary fixes for timer lists.
ssh access has been directly tested after this update.
