wifi: ath10k: add LED and GPIO controlling support for various chipsets 



Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984
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.
