I don't read anywhere Linus saying we should clutter drivers/*/Kconfig
with defaults. I think you're inverting things, it's much better
to select TWL4030_USB when you enable MACH_OMAP_RX51 then default y
if MACH_OMAP_RX51.

and you do that selection when the board is enabled otherwise the
drivers Kconfig will be cluttered with default Y if blabla.

But like I said before, it's Greg's ball. Personally, I think
you're taking the wrong approach.
