Using VMALLOC_END implies a presumption about the layout which is best

A generic version should replace this later.
As io.c has become nearly empty, omap_init_consistent_dma_size() is moved

The following commits break cpuidle on SH-Mobile ARM:
46bcfad cpuidle: Single/Global registration of idle states
e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state
This patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.
It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"
and "cpuidle_register_driver".

The runtime PM platform support stub in use by ARM-based SH/R-Mobile
platforms contains nothing that's specifically ARM-related and instead of
wholly generic to anything using the clock framework.
The recent runtime PM changes interact rather badly with the lazy
disabling of clocks late in the boot process through the clock framework,
leading to situations where the runtime suspend/resume paths are entered
without a clock being actively driven due to having been lazily gated
off.
In order to correct this we can trivially tie in the aforementioned stub
as a general fallback for all SH platforms that don't presently have
their own runtime PM implementations (the corner case being SH-based
SH-Mobile platforms, which have their own stub through the hwblk API --
which in turn has bitrotted and will be subsequently adapted to use the
same stub as everyone else), regardless of whether the platforms choose
to define power domains of their own or not.
This fixes up regressions for clock framework users who also build in
runtime PM support without any specific power domains of their own, which
was previously causing the serial console to be lost when warring with
lazy clock disabling.

*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.
*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.
To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.
Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.
This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:
a) Initializing the HW state from DT nodes during GPIO and pinmux device
probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
their probe until after the gpio and pinmux drivers have probed.
v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.
