Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 and ipq4019 based chipsets with on chipset connected led's using WMI Firmware API. The LED device will get available named as "ath10k-phyX" at sysfs and can be controlled with various triggers. adds also debugfs interface for gpio control.
