Modify OMAP McBSP driver to use omap hwmod framework and pm runtime APIs.
Created on top of linux OMAP (linux-omap-2.6 :omap-for-linus

OMAP: omap_device: API to modify SYSCONFIG register patch series
Did digital loopback testing on OMAP4430, OMAP3430, OMAP2430 and OMAP
1710 SDP boards.
Tested audio on 3430 SDP board (by me) and N810 (by Jarkko Nikula).
Tested PM with audio and verified the patch series does not cause regression.
PM testing comprises of suspend/resume between consecutive audio playback.
Support for suspend/resume in the middle of audio playback will be done by
audio guys on top of this patch series.
Patch series requires the following patch to be present

V4:
Rebased on omap-for-linus at commit 7cab8713b1ed0dab08ad6458f92a40b7ff4be619
V3:
* Fixed a few minor comments related to patch subject and patch description.
* Driver is adapted to handle the unique irq line (since this is the standard
from OMAP4).
* Removed duplication of memory address space entries in platform device model
and hwmod database for OMAP1/2 and 3.
* Put sysconfig in force idle when the mcbsp is freed (HW bug workaround for
the device to hit retention).
V2:
* Added omap_hwmod_lookup() in the callback to omap_hwmod_for_each_by_class()
to obtain hwmod data for sidetone. Previously this nesting of hwmod APIs was
prevented by the use of mutex.
* Added a revision member in hwmod database inorder to facilitate the driver
to differentiate between different OMAP.
* Created APIs to pass DMA params from McBSP driver to client drivers
* Cleaned up sound soc by removing the use of macros to obtain base address
and DMA channel number and instead use APIs exposed by the driver.
* Removed macros defined in mcbsp driver for data that is obtained from
hwmod database
V1:
* McBSP is designed to use multiple hwmods for a single device when the McBSP
device has sidetone feature.
* To avoid funcionality break of OMAP1 McBSP in between the series
and to keep the patches readable, implementation was done in two steps:
- First modify mcbsp driver to use platform_get* APIs
- then convert it to use hwmod framework for OMAP2+.
* API's like omap_device_noidle() and omap_device_default_idle() is used to
change the SYCONFIG register bits. This change is done to align with the
discussion on [2]
* Use '.rev' of omap_hwmod class to identify OMAP3 specific settings
* Use *ST_* macros for idlest_idle bit
* Incorporate other general review comments provided for hwmod adpatation
of other OMAP driver's (eg., do pdata free after a omap_device_build())
* Retain fclk even after pm_runtime adaptation to facilitate switching of
functional clock from one source to another
* Add member 'name' to omap_hwmod_addr_space struct so that the driver need
not rely on the order to get the proper resource [3].
