This patch series makes OMAP2PLUS musb module implemented in HWMOD FW way. It also implements musb driver to use the runtime pm apis. As per the OMAP usbotg specification[1] musb sysconfig register has to be set to force idle and force standby when not used and set smart idle/standby or no idle/standby during operation. otherwise core-off will be prevented by musb.

There will be another set of patches submitted with PM on musb. Version History: --------------- Version V4: Rebased the changes based on the re-orgnized patches submitted by Felipe. Fixed review comments received for V3. Dropped the idlepath power management patch with this series.

Re-arranged the patches in such a way that first migrate the musb driver to use the runtime PM apis and then added a patch to support offmode in idle path. Calling the runtime PM apis before disbaling the interupts in the idle path. Added the #ifdef CONFIG_PM_RUNTIME check in the musb core driver for calling the runtime PM APIs as non-omap platforms may not have the runtime pm enabled and clk_enable/disable should be called for them. Optimized the context save restore of musb registers only if the next state is going to offmode and previous state was offmode.

Removed the omap_hwmod.h inclusion from musb.h file which was breaking the non-omap platform build. Using the runtime pm apis in the idle path(interrupts disabled). Added the omap4 hwmod data base.
