changes in v2:
---
1. Addressed the concerns from Paul Wamsley around cleanups in
_enable_wakeup()/_disable_wakeup(), and left them intact
2. Updates in changelogs in the serial patch about changes
needed when dma support is added back for serial
3. Dropped 1/8 from v1 since its already pulled in
The patches are based of 'fixes-non-critical' branch of
'git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap' tree
since patch 1/8 from v1 was pulled in here.

OMAP UART IP needs manual idle modes based on functional 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 and tries to remove complete
sysc handling from serial driver.
Patches has been tested on OMAP4430 SDP and OMAP5 EVM where the console
sluggishness was observed without idle mode handling. CPUIDLE and
suspend tested ok on these devices.
Thanks to Vaibhav Bedia for testing on Beaglebone(AM33XX) with suspend and
also the UART async wakeup from suspend.
Thanks to Sourav Poddar for Beagle XM(OMAP3630) devices testing with
retention and offmode in Idle and suspend for non-DT builds.
Serial driver platform code still has one more function pointer
left which is used to trigger io_ring(). This one needs some
discussion with pincontrol driver folks on how to implement
such a feature with generic pincontrol driver.

ARM: OMAP2+: serial: Remove the un-used slave idle hooks
ARM: OMAP2+: hwmod: Remove sysc slave idle and auto idle apis
