Use the standard CMD_RET_* constants to clearly report errors from the
pca953x command. In addition, print error messages when I2C communication
fails.

gpio_get_value() should use PSR like Linux, not DR, because DR does not always
reflect the pin state, while PSR does. This is especially useful to detect a
short circuit on a GPIO pin configured as output, or to read the level of a pin
controlled by a non-GPIO IOMUX function.

This SoC is used in the Raspberry Pi, for example.
For more details, see:

http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf.
Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.

... rather than open-coding the register accesses.
However, gpio_request() typically stores the "label" parameter in a global
data structure. This causes problems when called from gpio_config_uart(),
since the code is running before relocation. To solve this, pass a NULL
string to gpio_request(), and modify gpio_request() not to touch the string
if it's NULL.

For files like the drivers/serial/serial.c, it must include the
platform file, as the CONFIG_SYS_NS16550_COM1 must reference to the
definition in the platform definition files.
Include the platform definition file in the config file, so that it
would decouple the dependence for the driver files.

This change is driven by need of general gpio_* functions,
which as their parameter are accepting the GPIO pin number, NOT
block and pin.
This makes the code alike to omap, and allows for using more
generic frameworks (e.g. software I2C).

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

This adds support for for the PCA9535/PCA9539 family of gpio devices which
have 16 output pins.
To let the driver know which devices are 16-pin it is necessary to define
CONFIG_SYS_I2C_PCA953X_WIDTH in your board config file. This is used to
create an array of {chip, ngpio} tuples that are used to determine the
width of a particular chip. For backwards compatibility it is assumed that
any chip not defined in CONFIG_SYS_I2C_PCA953X_WIDTH has 8 pins.
