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 follows the basics of what is decribed in
RM0091 Reference Manual 30.5.5 Suspend/Resume events .
We call enable/disable_sleep at suspend/resume, to make
sure the EC stays awake when USB is connected and active.
We also call clock_enable/disable_module, which is stubbed on
stm32f0, but can be used on other devices in the family.
This also fixes interrupt handling in usb_interrupt, by only
clearing interrupt bits that were handled instead of resetting
them all, which is racy, and can potentially lead to issues
if reset comes soon after a resume event.

and see that hammer prints USB suspend and USB resume lines.

Previously the usb driver used #ifs to select a mechanism to
enable and disable the DP pullup. This doesn't scale well,
especially when the knowledge of how to do this is not known
to the chip specific code, but instead is board specific (as
it is with the STM32F373).
This change uses the build systems ability to build chip family
specific files per build to select the appropriate behavior.
And on the STM32F3 family of parts it just calls out to a board
specific pair of connect/disconnect functions.
