omap: kill all section mismatch warning for omap2plus_defconfig
This patch will kill following section mismatch warnings:
WARNING: vmlinux.o(.text+0x24a00): Section mismatch in reference from the function zoom_twl_gpio_setup() to the (unknown reference) .init.data:(unknown)
The function zoom_twl_gpio_setup() references
the (unknown reference) __initdata (unknown).
This is often because zoom_twl_gpio_setup lacks a __initdata
annotation or the annotation of (unknown) is wrong.
WARNING: vmlinux.o(.text+0x24bfc): Section mismatch in reference from the function cm_t35_twl_gpio_setup() to the (unknown reference) .init.data:(unknown)
The function cm_t35_twl_gpio_setup() references
the (unknown reference) __initdata (unknown).
This is often because cm_t35_twl_gpio_setup lacks a __initdata
annotation or the annotation of (unknown) is wrong.

OMAP2+: io: split omap2_init_common_hw()
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.
