Moved, renamed, and deleted files

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

-/*	I think it would be in everyone's best interest to follow this
- *	guidelines when writing PDC wrappers:
- *
- *	 - the name of the pdc wrapper should match one of the macros
- *	   used for the first two arguments
- *	 - don't use caps for random parts of the name
- *	 - use the static PDC result buffers and "copyout" to structs
- *	   supplied by the caller to encapsulate alignment restrictions
- *	 - hold pdc_lock while in PDC or using static result buffers
- *	 - use __pa() to convert virtual (kernel) pointers to physical
- *	   ones.
- *	 - the name of the struct used for pdc return values should equal
- *	   one of the macros used for the first two arguments to the
- *	   corresponding PDC call
- *	 - keep the order of arguments
- *	 - don't be smart (setting trailing NUL bytes for strings, return
- *	   something useful even if the call failed) unless you are sure
- *	   it's not going to affect functionality or performance
- *
- *	Example:
- *	int pdc_cache_info(struct pdc_cache_info *cache_info )
- *	{
- *		int retval;
- *
- *		spin_lock_irq(&pdc_lock);
- *		retval = mem_pdc_call(PDC_CACHE,PDC_CACHE_INFO,__pa(cache_info),0);
- *		convert_to_wide(pdc_result);
- *		memcpy(cache_info, pdc_result, sizeof(*cache_info));
- *		spin_unlock_irq(&pdc_lock);
- *
- *		return retval;
- *	}
