of_device_ids (i.e. compatible strings and the respective data) are not
supposed to change at runtime. All functions working with of_device_ids
provided by <linux/of.h> work with const of_device_ids. So mark the
non-const function parameters and structs for OMAP2+ as const, too.

The definition

	static const char *omap3_boards_compat[] __initconst = {

defines a changable array of constant strings. That is you must not do:

	*omap3_boards_compat[0] = 'f';

but

	omap3_boards_compat[0] = "another string";

is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.

As the struct machine_desc member dt_compat is declared as

	const char *const *dt_compat;

making the arrays const is the better alternative over changing all
annotations to __initdata.

In the recent change to the reset function API (commit
7b6d864b), the mode argument changed from a
char to an enum. lpc23xx_restart() only handles REBOOT_SOFT and REBOOT_HARD,
but the new kernel code emits REBOOT_COLD (0) on reboots now which leads to
lpc32xx simply not rebooting (but halting).

This patch fixes this by just resetting unconditionally as on other platforms
(e.g. mach-bcm2835).

Pulling lpc32xx_watchdog_reset() into lpc23xx_restart() since the while() in
lpc23xx_restart() is part of the procedure anyway and lpc32xx_watchdog_reset()
isn't used anywhere else anymore.

We are using power domain state as RET and logic state as OFF. This
state is OSWR. This may not always be supported on ALL power domains. In
fact, on certain power domains, this might result in a hang on certain
platforms. Instead, depend on powerdomain data to provide accurate
information about the supported powerdomain states and use the
appropriate function to query and use it as part of suspend path.

powerdomain configuration in OMAP is done using PWRSTCTRL register for
each power domain. However, PRCM lets us write any value we'd like to
the logic and power domain target states, however the SoC integration
tends to actually function only at a few discrete states. These valid
states are already in our powerdomains_xxx_data.c file.

So, provide a function to easily query valid low power state that the
power domain is allowed to go to.

Based on work originally done by Jean Pihet <j-pihet@ti.com>
https://patchwork.kernel.org/patch/1325091/ . There is no attempt to
create a new powerdomain solution here, except fixing issues seen
attempting invalid programming attempts. Future consolidation to the
generic powerdomain framework should consider this requirement as
well.

Similar solutions have been done in product kernels in the past such
as:

Beaglebone white and beaglebone black differ in tiny little aspects.
This is the reason why we maintain seperate dts for these platforms.
However, there is no real way to decode from dtb which platform it is
since compatible and model name are the same for both platforms.

while maintaining compatibility for older zImages which might use old
beaglebone compatible flag for black as well.

  The delta is a largeish negative delta, due to revert of SMP support

   - minor DT fixes for shmobile
   - warning fix for UP builds on vexpress/spc
