ARM: OMAP2+: WDT: move init; add read_reset_sources pdata function pointer
The OMAP watchdog timer driver directly calls a function exported by
code in arch/arm/mach-omap2. This is not good; it tightly couples
this driver to the mach-omap2 integration code. Instead, add a
temporary platform_data function pointer to abstract this function
call. A subsequent patch will convert the watchdog driver to use this
function pointer.
This patch also moves the device creation code out of
arch/arm/mach-omap2/devices.c and into arch/arm/mach-omap2/wd_timer.c.
This is another step towards the removal of
arch/arm/mach-omap2/devices.c.
