firmware: altera-serial: add support for Arria 10 ...

Make FPGA specific settings configurable (padding, spi bits per word,
delays) and add Arria 10 support. The Arria 10 compatible is the same
as in the kernel patch "fpga manager: Add altera-ps-spi driver for
Altera FPGAs" (drivers/fpga/altera-ps-spi.c). The Arria 5 compatible
works unchanged.

This patch was tested with Arria 5 and Arria 10.

docs: fix hiding of chapter from imx.rst ...

The files 'mxs.rst' and 'imx.rst' used the same chapter headline:

    Freescale i.MXs

This confuses sphinx. It does not support having the same headline at
the same level twice and hides the other chapter. Just rename the
chapter heading to avoid that.

And rename the subchapter headline to 'MXS boards' for clarity.

ARM: i.MX50: Add support for i.MX50 based Amazon Kindle e-book readers ...

The Kindle Model No. D01100 (Kindle Wi-Fi), D01200 (Kindle Touch)
and EY21 (Kindle Paperwhite) are refered as the Kindle 4th and 5th generation.
Those models are based on an i.MX50 SoC and use LPDDR1 or LPDDR2 Memory.

The devices boot in internal boot mode from a build-in eMMC, alternatively
some devices may be set into USB-downloader mode by pressing a specific key
at startup.

Add support for the i.MX50 based Kindle device and make barebox a drop-in
replacement for the factory shipped u-boot image.

Notable features:
- Support for eMMC, USB, UART, I2C, SPI and Keys (except keyboard).
- LPDDR1 and LPDDR2 setup is done via DCD, the same imximage may be used
  for USB-startup and for installation.
- Support for vendor specific ATAGs that are required for the Kindle-System.
- usbserial barebox console access by pressing Select button at startup,
  alternatively full console support on connector J14.

state: Make pointing to the backend using a phandle the only supported method ...

All other methods are broken for some time already: When starting the
kernel the state code rewrites the state node in the device tree and
replaced the "backend" property with a phandle - even when the target
can't be described as a phandle. Since using phandles is the nicest way
to point to the storage device anyway remove the other methods.
