ANDROID: GKI: add wait_for_completion_interruptible_timeout to db845c symbol list

In commit 2a47da1c ("slimbus: qcom-ngd-ctrl: Add timeout for wait
operation"), the qcom-ngd-ctrl driver is changed to use the
wait_for_completion_interruptible_timeout() function, so add it to the
db845c symbol list so that the build properly works.

Fixes: 2a47da1c ("slimbus: qcom-ngd-ctrl: Add timeout for wait operation")
