misc: eeprom: eeprom_93cx6: Repair function arg descriptions

Copy-paste issue.  Looks like the kerneldoc style descriptions for
these functions were taken from existing functions with slightly
different argument names.

Fixes the following W=1 warnings:

 drivers/misc/eeprom/eeprom_93cx6.c:239: warning: Function parameter or member 'byte' not described in 'eeprom_93cx6_readb'
 drivers/misc/eeprom/eeprom_93cx6.c:239: warning: Excess function parameter 'word' description in 'eeprom_93cx6_readb'
 drivers/misc/eeprom/eeprom_93cx6.c:280: warning: Function parameter or member 'bytes' not described in 'eeprom_93cx6_multireadb'
 drivers/misc/eeprom/eeprom_93cx6.c:280: warning: Excess function parameter 'words' description in 'eeprom_93cx6_multireadb'
