tsec: Conditionally turn off clock in suspend
Problem:
=======
In current implementation of tsec_poweroff, tsec clock is getting
turned off unconditionally.
During suspend-resume operation, there is an issue in MB1 as
explained in bug 3796711 (comment 16). Due to this, when
tsec_poweroff function is called for second suspend operation,
tsec clock is turned off even when the power state variable
"pdata->power_on" is not set to true or 1.
This causes the following warning from clock driver highlighting
that tsec clock is already disabled.

Solution:
========
There is a check present in tsec_poweroff function to conditionally
call tsec_prepare_poweroff only if TSEC is powered on. Use the
same check to conditionally call tsec_disable_clk

This patch does changes needed in cache flush and
carevout related memory apis which are different
