In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

This CL fixes that i2c driver will prompt "I2C chx reset cause 1" issue
when one i2c transaction is separated into at least three i2c_xfer and
I2C_XFER_START flag is set at least two times.
eg.
- i2c_xfer with I2C_XFER_START flag
- i2c_xfer with I2C_XFER_START flag <= this will cause reset
- xxx
- i2c_xfer with I2C_XFER_STOP flag
BRANCH=none
BUG=none
TEST=no i2c reset on Asurada, Drawcia, and ADL-RVP.

There is an option in the task_set_event function which force
the calling task to wait for an event. However, the option is never
used thus remove it.

Some devices (like the keyboard, CBI) need I2C access pretty early.
Until now I2C would get initialized pretty late in a hook, which was far
too late for some stuff.
As a result from this change, CONFIG_I2C_MASTER now implies the i2c_init()
function will be called at board boot. Some chips (cr50, host tests)
needed a stub i2c_init in order to compile cleanly.

Opt for 7bit slave addresses in EC code. If 8bit is
expected by a driver, make it local and show this in
the naming.
Use __7b, __7bf and __8b as name extensions for i2c/spi
addresses used in the EC codebase. __7b indicates a
7bit address by itself. __7bf indicates a 7bit address
with optional flags attached. __8b indicates a 8bit
address by itself.
Allow space for 10bit addresses, even though this is
not currently being used by any of our attached
devices.
These extensions are for verification purposes only and
will be removed in the last pass of this ticket. I want
to make sure the variable names reflect the type to help
eliminate future 7/8/7-flags confusion.

The I2C function of IT8320 is used as the slave.
The slave channel A can support 16-byte FIFO for
read and write data. The enhanced I2C channel D,
E and F can support read and write 256-byte data
by DMA mode.
When master transmits data to slave, the interrupt
signal will generate, and the data will be saved
to buffer.

- To i2c channel(d/e/f), we remove instructions that aren't necessary.
- Changes of i2c_reset():
Before the change, we try to send a START/STOP bit if we get a reset.
But i2c_unwedge() already done it, so we just need reset i2c module
in i2c_reset().
- Add enhanced_i2c_start() to channel(d/e/f) for each transaction start:
We prepare transaction start by calling i2c_reset(),
but this doesn't match the definition of i2c_reset(),
so we correct it.

This timeout is described in SMBus specification (25ms).
Some I2C devices may required longer clock stretch
(The I2C specification does not specify any timeout conditions
for clock stretching).
So we increase this timeout to maximum.
NOTE:
Because this codebase already handle timeout of an I2C transfer,
so maybe we can disable this mechanism.
But we don't have any register to execute this,
so we maximize the timeout.
