ARM: shmobile: Select CONFIG_ZONE_DMA when CONFIG_ARM_LPAE is enabled

Most IP cores on ARM Renesas platforms can only address 32 bits of
physical memory for DMA. Without CONFIG_ZONE_DMA enabled and with the
recent CMA highmem allocation support, the default CMA zone is reserved
above the 4GiB limit when LPAE is enabled, resulting in various driver
failures.

Fix the problem by selecting CONFIG_ZONE_DMA. Other options to
investigate in the future would be to either enable IOMMU support or use
custom CMA reservations for peripherals not supporting LPAE.

While not a strict dependency, the "[PATCH 0/4] Low/high memory CMA
reservation fixes" series is also required to fix a different but related CMA
allocation problem.

Merge tag 'backport/v3.14.24-ltsi-rc1/of-20141117' into backport/v3.14.24-ltsi-rc1/mach-shmobile

of: correct of_console_check()'s return value

The comments above of_console_check() say that it will return TRUE if it
registers a preferred console, but add_preferred_console() uses a
0-equals-success convention, so this leaves of_console_check() with an
inconsistent policy for its return values.

Fortunately, nobody was actually checking the return value of
of_console_check(), so this isn't significant at the moment.

But let's match the comments, so we're doing what we say.

of: Enable console on serial ports specified by /chosen/stdout-path

If the devicetree specifies a serial port as a stdout device, then the
kernel can use it as the default console if nothing else was selected on
the command line. For any serial port that uses the uart_add_one_port()
feature, the uart_add_one_port() has all the information needed to
automatically enable the console device, which is what this patch does.

With this change applied, a device tree platform can be booted without
any console= parameters on the command line and the kernel will still be
able to determine its console.

Tested on QEMU Versatile model and i.MX

The devicetree has a binding for specifying the console device in the

adds an API for testing if a device node is a console, and adds a
preferred console entry if it is.

since it is unused.

ARM: shmobile: r8a7740: Use SoC-specific 48-bit CMT compat string

In general Renesas hardware is not documented to the extent
where the relationship between IP blocks on different SoCs can be assumed
although they may appear to operate the same way. Furthermore the
documentation typically does not specify a version for individual
IP blocks. For these reasons a convention of using the SoC name in place
of a version and providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
a number of drivers for Renesas hardware. The purpose of this patch is to
make use of the SoC-specific CMT compat string for the r8a7740 48-bit CMT
clock source.

The kernel command line is left as-is, earlyprintk is used in
