This series of patches replaces the custom 93cx6 EEPROM read functions in
the 8250_exar driver with the eeprom_93cx6 driver. This removes duplicate code
and improves code readability.

In order to use the eeprom_93cx6 driver a quirk needed to be added to add an
extra clock cycle before reading from the EEPROM. This is similar to the
quirk in the eeprom_93xx46 driver.

More details in associated patch and mailing list discussion with
Andy Shevchenko about these changes:
