RK3326: fix Soysauce power LED polarity, surface DISABLE POWER LED

Browse Source 
Live debugging on the Soysauce (USB SSH, watcher on the led sysfs while
the user drove the ES menu) showed the whole chain working but the LED
responding inverted: the blue power LED is wired active high, so the
GPIO_ACTIVE_LOW in the DTS made "off" light it and "on" darken it
(heartbeat looked normal because a blink is a blink upside down). Flip
the polarity and default the LED on so early boot keeps the stock look.
The led-red node was a phantom: the physical red LED belongs to the
charger IC and toggling GPIO0_A5 changes nothing, so drop it.

The DISABLE POWER LED switch in ES is gated on DEVICE_PWR_LED_CONTROL,
which sits in the 999-export allowlist but was never set by any quirk,
so the item was invisible on every device. Set it for the R36S family.
