Add the device tree node for the ir-spi driver which enable the
ir led for remote controlling.
This patch sets first the GPR3[3] gpio line as a regulator-fixed
for enabling an external regulator which powers the IR LED.
Removes also the default assignment of the GPG3[5] and GPG3[7]
related to the SPI3 line.
