first round name simplification. drop the <component>_ prefix.
the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong
