This is no longer needed as the device specific wake-up event
can now be specified with interrupts-extended property where
the second interrupt is the pinctrl-single register, such as
the UART3 RX pin.

Note that twl4030_omap3.dtsi needs to set WAKEUPENABLE for
off-idle to properly trigger the PMIC scripts. And GPIO pins
still need to set WAKEUPENABLE for wake-up events.

Compared to legacy booting, we don't have wake-up events enabled
for device tree based booting. This means that if deeper idle
states are enabled, the device won't wake up to UART events and
seems like it has hung.

Let's fix that by adding the wake-up interrupt. Note that we
don't need to set the PIN_OFF_WAKEUPENABLE any longer, that's
handled by the wake-up interrupt when the serial driver does
request_irq on it.

Tested with the following on omap3-overo-summit that has the
ES2.1 omap:

#!/bin/bash

uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
        echo 3000 > $uart/autosuspend_delay_ms
done

uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
        echo enabled > $uart/wakeup
        echo auto > $uart/control
done

echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode

# grep -i uart /proc/interrupts

The sub-mailbox devices are added to the Mailbox DT nodes on
OMAP2420, OMAP2430, OMAP3, AM33xx, AM43xx, OMAP4 and OMAP5
family of SoCs. This data represents the same mailboxes that
used to be represented in hwmod attribute data previously.
The node name is chosen based on the .name field of
omap_mbox_dev_info structure used in the hwmod data.

We've had deeper idle states working on omaps for few years now,
but only in the legacy mode. When booted with device tree, the
wake-up events did not have a chance to work until commit
3e6cee17 ("pinctrl: single: Add support for wake-up interrupts")
that recently got merged. In addition to that we also needed
commit 79d97015 ("of/irq: create interrupts-extended property")
that's now also merged.

Note that there's no longer need to specify the wake-up bit in
the pinctrl settings, the request_irq on the wake-up pin takes
care of that.

The RFBI node for OMAP DSS was left out when adding the rest of the DSS
nodes, because it was not clear how to set up the clocks for the RFBI.

However, it seems that if there is a HWMOD for a device, we also need a
DT node for it. Otherwise, at boot, we get:

WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2542 _init+0x464/0x4e0()
omap_hwmod: dss_rfbi: doesn't have mpu register target base

Now that v3.17-rc3 contains a fix 8fd46439 ("ARM: dts:

required by the RFBI, let's add the RFBI node to get rid of the

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