ath79: restore gpio-export on TL-WDR3600/4300
This partially reverts commit 32144ba275d163ce6e7d93546ab4414f03f508fb. This commit replaced gpio-exports in favor of gpio-hogs for enabling USB power at boot, but this rids the user of control of the USB port power present on this device for a long time. It was agreed on a mailing list [1] that this is not the way to go, and this patch breaks a very common use-case of WWAN modem reset by power cycle, used on a lot USB equipped routers, hence revert this change until a better solution can be found.
