[PATCH 2/3] wifi: ath10k: start LED with the previous defined cdev brightness

[Christian Marangi]

In preparation for DT support for LED, change ath10k_leds_start to init
the LED to the previous defined cdev brightness.

The LED is set to OFF by default since we can't understand the previous
state of the LED due to a limitation in the WMI calls exposed by the fw.
