To reduce kernel source file data duplication, share struct
omap_hwmod_mpu_irqs arrays across OMAP2xxx and 3xxx hwmod data files.
Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Previously, struct omap_hwmod_mpu_irqs arrays were unterminated; and
users of these arrays used the ARRAY_SIZE() macro to determine the
length of the array.  However, ARRAY_SIZE() only works when the array
is in the same scope as the macro user.

So far this hasn't been a problem.  However, to reduce duplicated
data, a subsequent patch will move common data to a separate, shared
file.  When this is done, ARRAY_SIZE() will no longer be usable.

This patch removes ARRAY_SIZE() usage for struct omap_hwmod_mpu_irqs
arrays and uses a sentinel value (irq == -1) as the array terminator
instead.

omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.

This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.

Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.

We can keep everything sys_timer and gptimer.c related code in

Later on we can also remove timer-mpu.c, as it can be called from
omap4_timer_init function.

This allows us to get rid of confusing existing files. We currently
have timer-gp.c, timer-mpu.c, and patches have been posted to add
dmtimer.c. There's no need to have these multiple files, we can
put everything into timer.c.

This is needed for the following patches so we can initialize the

As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
rest of the hardware timers to happen with an arch_initcall.
