OMAP UART IP needs manual idle modes based on state of the

implemented in platform code.

This however breaks in case of device tree because of missing
idle handling.

The series tries to address the issue

Patches has been tested on OMAP4 and OMAP5 devices where the console
slugishness was observed without idle mode handling. CPUIDLE and
suspend tested ok on these devices.

Need help in testing on OMAP2, OMAP3 and AM3XXX devices.

Tested this series on omap3630 beagle board for:
1. Retention in idle and suspend.
2. Off mode in idle and suspend.

Tested-by: Sourav Poddar<sourav.poddar@xxxxxx>
try setting autosuspend_delay to -1
Also try DT boot and try to wakeup from echo mem>  /sys/power/state by
sending data through UART console.

Suspend/resume with dt is not functional with the current mainline.
