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.

After waking from Low Power Mode, TCPMv2 always performs TCPC
initialization. Issuing soft reset during initialization leads to
lose information about DRP result and set CC lines to Rd. When
attaching sink, TCPC will report that nothing is connected and as a
result TCPMv2 will enable DRP and go to Low Power Mode again.
When LPM debounce delay is longer than tDRP (time in which TCPC will
advertise source and sink, between 50ms and 100ms according to Type-C
specification), then TCPC will always find connection before going to
Low Power Mode. If it is smaller, TCPMv2 will loop between LowPowerMode
and DRPAutoToggle states.

TEST=Run EC on Volteer board. Check if TCPC works.
TEST=Change PD_LPM_DEBOUNCE_US to 10ms and check if sink (eg. pendrive)
is detected correctly.

At present boards includes the private header of some of the drivers.
This is not ideal but it works. For Zephyr we don't really want to
access headers in private driver directories.
Instead, create public headers for the five drivers needed by the
Zephyr volteer build. For now, include the public header in the
private header (the one included by the EC code), so that fewer code
changes are required.

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.
