[PATCH v2 0/8] USB preparation for "allyesconfig"

[Tom Rini]

Hey all,

In order for "allyesconfig" to work we need to start out by either
declaring some drivers as invalid for the target (as they have
non-trivial problems to solve such as architecture headers being
required), remove drivers because no one is using them anymore, or do
the easy fixes required.

This series takes care of drivers/usb/ for allyesconfig by adding
dependencies in a number of places and removing some unused drivers.

Changes in v2:
- Pickup Marek's tag when applicable.
- Drop the musb portion as Peter Robinson had an existing series for it
- Reword the commit message on the two gadget driver removals.
- Add this cover letter.
