arm64: dts: exynos: Enable ir-spi in the TM2 and TM2E boards
Add the device tree node for the ir-spi driver which enables 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 GPG3[7] related to the MOSI line of the SPI3 bus.
