This patch does two main things

- It implements the crash console UART init in assembly, as a
  hard-coded 115200 8N1 assumed from the 24 MHz clock.

  If the clock setup code has not run yet, this code can't work but,
  setting up clocks and clock-gates is way out of scope for this type of
  recovery function.

- It adds code to write a character out of the NXP UART without using any
  stack-based operations when doing so.

- Provides support for crash console in DCE or DTE mode.

- Adds a simple register read/write abstraction to cut-down on the
  amount of typing and text required to access UART registers in this driver.

- Adds a console getc() callback.

- Adds a console putc() callback, translating '\n' to '\r' + '\n'.

- Initializes the MXC UART, take a crude method of calculating the
  BAUD rate generator. The UART clock-gates must have been enabled prior
  to launching the UART init code.
  Special care needs to be taken to ensure the UBIR is initialized before the
  UBMR and we need to ensure that UCR2.SRST comes good before trying to
  program other registers associated with the UART.

DMA is always used in mmc driver. So the buffer address should
always follow the DMA limitation.

There're same requirement in mmc_read_blocks()/mmc_write_blocks()
on parameter buf. Since parameter buf comes from io_block driver,
it's already handled in io_block driver.

At here, just make the minimum address alignment on 16 chars.

Functions provided by stdio.h such as printf and sprintf are available
in the codebase, but they add a lot of code to the final image if they
are used:

- AArch64: ~4KB
- AArch32: ~2KB in T32, ~3KB in A32

tf_printf and tf_snprintf are a lot more simple, but it is preferable
to use them when possible because they are also used in common code.

We had exit but we didn't have atexit, and we were calling panic and
tf_printf from exit, which generated a dependency from exit to them.
Having atexit allows to set a different function pointer in every image.

Mbebtls include paths are controlled by the user using the variable
MBEDTLS_DIR and they are out of the TF source tree. Since these
includes have a different origin it is better to move them to a
different variable.

paths.

The functions cci_enable_snoop_dvm_reqs and cci_disable_snoop_dvm_reqs write
in the SNOOP_CTRL_REGISTER of the slave interface and it polls the status
register to be sure that the operation is finished before leaving the
functions. If the write in SNOOP_CTRL_REGISTER is reordered after the first
read in the status register then these functions can finish before
enabling/disabling snoops and DVM messages.

The CCI500 TRM specifies:

	Wait for the completion of the write to the Snoop Control Register
	before testing the change_pending bit.
