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.

Changes in v3:
- Rebased to v6.12-rc1.
- Minor commit message rewording.
- Replace CTI_EE_MASK_OSC_FREQ_UPPER/LOWER with a single define in patch 4.
- Add patch 5 from Andy Shevchenko: "serial: 8250_exar: Group CTI EEPROM offsets by device".

Everything is fine except one minor (in patch 1) and one more serious
(see patches 3 & 4) issue. I just commented on them. Fix and send a final
v4, my tags are already there and you may keep them.

Thank you!

Thank you, I will fix and resend.
