Subject: [PATCH 4.19 72/84] rtc: brcmstb-waketimer: add missed clk_disable_unprepare

From: Chuhong Yuan <hslester96@...il.com>

commit 94303f8930ed78aea0f189b703c9d79fff9555d7 upstream.

This driver forgets to disable and unprepare clock when remove.
Add a call to clk_disable_unprepare to fix it.

Fixes: c4f07ecee22e ("rtc: brcmstb-waketimer: Add Broadcom STB wake-timer")
