We ran into this same problem in OMAP too. The solution we ame up with is to just power-up all UARTs and an inactivity timer disables unused UART clocks. I tried a solution to this in the 8250 driver, but the bigger problem is that the 8250 driver is orphaned. Patches to add/fix features for the 8250 driver go largely ignored on the serial list.
