x86/platform/intel-mid: Add Power Management Unit driver
Add Power Management Unit driver to handle power states of South Complex devices on Intel Tangier. In the future it might be expanded to cover North Complex devices as well. With this driver the power state of the host controllers such as SPI, I2C, UART, eMMC, and DMA would be managed.
