ar71xx: rbspi: clarify USB power gpios action
The gpios that control power toggle for USB on the RouterBOARD devices are active low _off_ switches. When they are active (low), power is off. When they are inactive (high), power is on. Rename GPIO defines, set gpios to GPIOF_ACTIVE_LOW for consistency and reflect their true action in the display name. This brings openwrt code in line with OEM.
