1. Add flash control module for emulation board.
2. Fix system jump for Andes core.
3. Change the physical size of the flash on the chip to 256KB.
note:
1. Only IT839x series supports flash write protect by registers.
2. Static DMA method of flash code only for IT839x series and IT838x Dx.

This unifies all the EC header files to use __CROS_EC_FILENAME_H
as the include guard. Well, except for test/ util/ and extra/
which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

Our existing GPIO macros use port# / gpio#, but the concept of different
GPIO ports does not exist on the mec1322. Therefore, add new GPIO macros
for chips which do not have distinct GPIO ports.

In the gpio_info struct, we had a irq_handler pointer defined even
though a majority of the GPIOs did not have irq handlers associated. By
removing the irq_handler pointer out of the struct, we can save some
space with some targets saving more than others. (For example, ~260
bytes for samus_pd).
This change also brings about a new define:
GPIO_INT(name, port, pin, flags, signal)
And the existing GPIO macro has had the signal parameter removed since
they were just NULL.
GPIO(name, port, pin, flags)
In each of the gpio.inc files, all the GPIOs with irq handlers must be
defined at the top of the file. This is because their enum values from
gpio_signal are used as the index to the gpio_irq_handlers table.

Previously if you were working on a single board you had to add BOARD=
to all of your make command lines. Now if you are in a board directory
you can just use "make", or "make clean", or any other top level make
command.
This commit also adds support for a top level "make flash" command that
can be used from the board directories as well. This command uses
openocd and requires that the board provides an openocd-flash.cfg file.

This is a straightforward conversion of existing tables
into X-Macro style definitions for the GPIO alternate
functions. This change in itself, is not particularly
powerful, but having all GPIO settings in a single file
makes a board easier to understand.

Previously each board.h and board.c contained an enum and an array
for gpio definitons that had to be manually kept in sync, with no
compiler assistance other than that their lengths matched.
This change adds a single gpio.inc file that declares all gpio's
that a board uses and is used as an X-macro include file to
generate both the gpio_signal enum and the gpio_list array.
