ath79: replace gpio-cascade on Buffalo WZR-HP-G300NH

Browse source 
The GPIO cascade driver is a downstream-only driver and the Buffalo
WZR-HP-G300NH is its only user for now. Recently, a similar and
independently developed driver 'gpio-line-mux `which serves the same
purpose was accepted upstream and backported here. Use that instead the
downstream driver.
