Split omap2_init_common_hw() into two functions. The first, omap2_init_common_infrastructure(), initializes the hwmod code and data, the OMAP PM code, and the clock code and data. The second, omap2_init_common_devices(), handles any other early device initialization that, for whatever reason, has not been or cannot be moved to initcalls or early platform devices. This patch is required for the hwmod postsetup patch, which allows board files to change the state that hwmods should be placed into at the conclusion of the hwmod _setup() function. For example, for a board whose creators wish to ensure watchdog coverage across the entire kernel boot process, code to change the watchdog's postsetup state will be added in the board-*.c file between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls.
