ARM: shmobile: koelsch: Remove legacy C board code

All features supported by the Koelsch legacy C board code are now
supported by the multiplatform code, it's thus time to say bye to the
legacy code. Nobody should miss it.

ARM: shmobile: lager: enable USB3.0

Since the PHY of USB3.0 and EHCI/OHCI ch2 are the same, the USB3.0

phy phy-e6590100.usb-phy.3: phy init failed --> -16
xhci-hcd: probe of ee000000.usb failed with error -16

If so, we have to unbind the EHCI/OHCI ch2, and then we have to bind
the USB3.0 driver as the following:

  echo 0000:02:02.0 > /sys/bus/pci/drivers/ehci-pci/unbind

  echo ee000000.usb > /sys/bus/platform/drivers/xhci-hcd/bind

Note that there will be pinctrl-related error messages if both
internal PCI and USB3.0 are enabled but they should be just ignored:

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

of: Create of_console_check() for selecting a console specified in /chosen

The devicetree has a binding for specifying the console device in the
/chosen node, but the kernel doesn't use it consistently. This change
adds an API for testing if a device node is a console, and adds a
preferred console entry if it is.

At the same time this patch removes the of_device_is_stdout_path() API
since it is unused.
