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:

Changes in v2:
- Dropped patch 3 "misc: eeprom: eeprom_93cx6: Replace printk(KERN_ERR...) with pr_err()".
- Moved Kconfig change into main patch.
- Moved quirk define into struct eeprom_93cx6.
- Moved quirk check function into eeprom_93cx6.h.
- Refactored cti_read_osc_freq() based on feedback.
- Minor commit message formatting fixes.
