The Wi-Fi module of Pine64 is powered via DLDO4 and ELDO1 (the latter one provides I/O voltage).
Add device node for it.
Although the Wi-Fi module is an external module which should be inserted to a header, according to my personal talk with TL Lim, he does not want this header to be used as GPIO (so it's with 2.0mm pitch, not 2.54mm as other GPIO headers).
