cld:enable sleep mode

PCIE SOC Wake needs to be set so that target will go sleep or low
power mode. But before loading the firmware target clocks won't be
set properly. In this case host cannot wakeup target properly.

So till the driver is loaded PCIE wake will be set to awake.
Once the driver is loaded PCIE wake will be set to sleep mode.

With this max perf mode i.e keeping the target always awake
is disabled as well.
