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.

The extentions were added to make the compiler perform most
of the verification that the conversion was being done correctly
to remove 8bit addressing as the standard I2C/SPI address type.
Now that the compiler has verified the code, the extra
extentions are being removed

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.

TEST=Verify charging from PD and WPC as follows:
1. Charge with PD charger. Place DUT on WPC charger.
-> PD charger continues to charge.
2. Unplug PD charger.
-> WPC starts charging as GPP.
3. Plug PD charger.
-> PD charger starts charging at 2A@9V
TEST=Verify OTG and WPC functionality as follows:
1. Plug fan to USB port:
-> Fan spins
2. Place DUT on WPC charger:
-> WPC starts charging as GPP. Fan continues to spin.
3. Remove DUT from WPC charger:
-> Fan continues to spin.
4. Do 1 and 2 then unplug USB fan:
-> WPC starts charging.
