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.
