staging: comedi: addi_eeprom: cleanup i_EepromReadMainHeader()

Add namespace by renaming this CamelCase function to
addi_eeprom_read_info().

Remove the 'type' parameter. This parameter is a char pointer to the
string name of the eeprom type used on the board. This can be found
when needed using the dev pointer.

Change the parameter order so that the comedi_device pointer is passed
first.

The return value is always 0 and it's never checked. Change it to void.
