Fix the gpio-leds node to match the LEDs on RPI2.

Browse source 
The 'pwr' LED is connected to GPIO pin 35 (active high) and the 'act' LED
is connected to GPIO pin 47 (active high).

Remove the GPIO pin 47 from reserved pins list, previously it was used to
signaling the SD Card presence and now it is used by act LED.
