- re-enable console suspend, which seems to be broken with elogind when
suspending (kernel gets hung up indefinitely in vt_waitactive)
- add a suspend hook to work around the musb driver not allowing the
device to suspend
Based on my testing, this option seems to prevent suspending via
elogind (using `loginctl suspend`). When console suspend is disabled,
the kernel gets hung up in the call to vt_waitactive, and elogind times
out trying to suspend.
