From: Santosh Shilimkar <[email protected]> UART IP slave idle handling now taken care by runtime pm backend(hwmod layer) so remove the hackery from the driver.
As discussed on the list, in future if dma mode needs to be brought back to this driver, UART sysc handling needs to be updated in framework such a way that no-idle/force idle profile can be supported. Given the broken dma mode for OMAP uarts, its very unlikely.
