OMAP UART IP needs manual idle modes based on state of the
IP. Currently this is handled by the driver with function pointers
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.

modes
SERIAL: OMAP: Remove the idle handling from the driver
