arm: mach-omap: Change file flags in emmc handler ...

This handler tries to read from a file descriptor with 'write only'
flags and fails. Add read permissions for the file, so the handler can
read the partition layout.

state: Create alias in of_state_fixup() ...

When the kernel device tree is fixed up we assume that it doesn't
have a state node, so we must also assume that it doesn't have
a alias. Create it.

state: warn when a state node will be overwritten ...

People do not seem to know that a state node in the kernel
device tree will be overwritten by barebox. Print a warning
when this happens so that people can get an idea why changes
in the kernel device tree state node do not have any effect.

mci: be more verbose about wrong bus-width ...

If configured or default bus-width is wrong for the current hardware,
registration of card/emmc is likely to fail.  This patch adds more verbosity
in the case of a failed detection:

    | omap-hsmmc 48060000.mmc: registered as 48060000.mmc
    | mmc0: detected MMC card version 4.41
    | mmc0: Changing MMC bus width failed: -110

clk: socfpga: add arria10 clk drivers ...

Arria10 has a (slightly) different clock controller than the
Cyclone5. Add new drivers for it.

This driver only reads out the setup and builds the clocktree,
it does not setup any clocks.

ARM: socfpga: add arria10 support ...

Arria10 is a SoC + FPGA like the Cyclone5 SoCFPGA that
is already supported in barebox.
Both a the same in some parts, but totaly different in
others. Most of the hardware blocks are the same in the
SoC parts. The OCRAM is larger on the Arria10 and the
SDRAM controller is different.
The serial core only supports 32bit accesses (different to
the 8bit accesses on the Cyclone5).

As Arria10 has 256KB of OCRAM, it is possible to fit a larger
barebox (and/or use PBL) instead of the two stage bootprocess
used on the Cyclone5 and its 64KB OCRAM.
