Add GPIO-only r8a7779 PFC support V2.

Only regular GPIOs are supported at this time. GPIO_FN are not
supported because they require variable bit width support in be
the shared pfc code.

Initial support for the r8a7779 SoC and the Marzen board (V2).

Only SCIF ports and the TMU are supported at this point.

To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console
due to virtual address space collisions with the ARM kernel.

BUILD_BUG_ON is defined in linux/kernel.h but that is not included by the
asm/bug.h header which uses it. This causes a build error:

...include/linux/mtd/map.h: In function 'inline_map_read':
...include/linux/mtd/map.h:408:3: error: implicit declaration of function
'BUILD_BUG_ON' [-Werror=implicit-function-declaration]

The check is not essential and is not present for other architectures, so
just remove it.

The restart support was missed from the initial imx6q submission.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

Remove the:
	KERN_CRIT "RESET: Rebooting system\n" (lpc32xx)
	KERN_CRIT "RESET: shutting down/rebooting system\n" (u300)

printk from the restart handler; we already print such a message from
kernel_restart() in kernel/sys.c:

	KERN_EMERG "Restarting system.\n"

so this is unnecessary.

S3C2412/S3C2416/S3C2443 use a special register to signal the reset to
the processor and used therefore the s3c24xx_reset_hook mechanism in the
s3c24xx-specific arch reset.

This patch introduces restart functions for these architectures,
moves the board files to them and removes the s3c24xx_reset_hook
infrastructure, as all users are gone.
