arm: debug: import debug files from Linux 3.16

U-Boot does not have arch/arm/kernel, include/uapi directories,
This commit copies files as follows:

  Location in Linux               -> Location in U-Boot

  arch/arm/kernel/debug.S         -> arch/arm/lib/debug.S
  arch/arm/include/debug/8250.S   -> arch/arm/include/debug/8250.S
  include/uapi/linux/serial_reg.h -> include/linux/serial_reg.h

arm: debug: add Kconfig entries for lowlevel debug

We have not had a good method to debug the early boot stage such as
lowlevel_init function.  I guess developers generally use dedicated
debuggers for that, but it is difficult in some cases.
(For example, my debugger cannot connect to the ARM processor when
it is in the secure state.  It sometimes happens when I need to
debug the early boot stage on ARM SoCs with secure extension.)

The low level debug feature in Linux would be also helpful for U-boot
when we are stucking in nasty problems where the console is not
available yet.

You have to enable CONFIG_DEBUG_LL to use this feature.
For now, only 8250-compatible UART devices are supported.
You can add a header file under arch/arm/include/debug/ directory
to support your UART device if necessary.

arm: debug: adjust for U-Boot

Because CONFIG_MMU is never defined in U-Boot,
the non-MMU code in debug.S is always used.

Unfortunately, the number of arguments of the addruart macro
in Linux is different between MMU and non-MMU.
This causes a build error when importing some debug macros
using the third argument. (For ex. arch/arm/include/debug/exynos.S)
Pass the third argument to the non-MMU addruart to avoid such a problem.

arm: socfpga: Add I2C support to SoCFPGA

This patch adds I2C support for the SoCFPGA. Using the designware I2C
controller driver. It supports all 4 I2C busses on the SoCFPGA.

The designware I2C driver has now been converted to the
CONFIG_SYS_I2C framework. So lets enable it on SoCFPGA.

Tested on SoCrates.

video: speedup writing strings to fb console

With enabled framebuffer console the printenv command can take several
seconds to complete. This patch temporarily disables cache flush when
writing strings to fb console. Then there is no noticable delay anymore.

Tested with imx6 hdmi framebuffer.
