ncr53c8xx: remove ancient configuration macros

It has not been possible to set CONFIG_SCSI_NCR53C8XX_FORCE_SYNC_NEGO, CONFIG_SCSI_NCR53C8XX_DISABLE_MPARITY_CHECK, and CONFIG_SCSI_NCR53C8XX_DISABLE_PARITY_CHECK through the configuration system since v2.1.20. Remove these ancient macros.

To enable (or disable) the functionality they covered one should edit a header file and set related preprocessor macros. Since this is actually a documented feature those related macros remain available.

---
Untested.

Note that the documentation still contains
insmod ncr53c8xx

Besides insmod being outdated, the modules that use ncr53c8xx's code appear to be NCR_Q720_mod.ko and zalon7xx.ko. So the documentation needs probably to be updated to reflect this.

     This frequency can be changed later with the "setsync" control command.
     0 means "asynchronous data transfers".
 
-CONFIG_SCSI_NCR53C8XX_FORCE_SYNC_NEGO (default answer: n)
-    Force synchronous negotiation for all SCSI-2 devices.
-    Some SCSI-2 devices do not report this feature in byte 7 of inquiry 
-    response but do support it properly (TAMARACK scanners for example).

 CONFIG_SCSI_NCR53C8XX_NO_DISCONNECT   (default and only reasonable answer: n)
     If you suspect a device of yours does not properly support disconnections,
     you can answer "y". Then, all SCSI devices will never disconnect the bus
