staging: comedi: rti800: remove am9513.h header

Browse Source 
This driver is the only file that includes the am9513.h header and
nothing from that header is actually used. Using the macros provided
by am9513.h is a bit ugly due to having to predefine a number of
additional macros to handle the low-level I/O to the Am9513 device.

Just remove the header and the unused I/O helpers in the rti800
driver. If support for the am9513 is added later it wil be implemented
properly at that time.
