Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

-/*
- *	Operating System Services (OSS) chip handling
- *	Written by Joshua M. Thompson (funaho@jurai.org)
- *
- *
- *	This chip is used in the IIfx in place of VIA #2. It acts like a fancy
- *	VIA chip with prorammable interrupt levels.
- *
- * 990502 (jmt) - Major rewrite for new interrupt architecture as well as some
- *		  recent insights into OSS operational details.
- * 990610 (jmt) - Now taking full advantage of the OSS. Interrupts are mapped
- *		  to mostly match the A/UX interrupt scheme supported on the
- *		  VIA side. Also added support for enabling the ISM irq again
- *		  since we now have a functional IOP manager.
