Revert "staging: vchiq_arm: Create keep-alive thread during probe"

The commit 86bc88217006 ("staging: vchiq_arm: Create keep-alive thread
during probe") introduced a regression for certain configurations,
which doesn't have a VCHIQ user. This results in a unused and hanging
keep-alive thread:

  INFO: task vchiq-keep/0:85 blocked for more than 120 seconds.
        Not tainted 6.12.34-v8-+ #13
  "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
