[PATCH v3 08/12] i2c: designware: Discard Cherry Trail model flag

[Serge Semin]

A PM workaround activated by the flag MODEL_CHERRYTRAIL has been removed
since commit 9cbeeca05049 ("i2c: designware: Remove Cherry Trail PMIC I2C
bus pm_disabled workaround"), but the flag most likely by mistake has been
left in the Dw I2C drivers. Lets remove it.

Changelog v3:
- Since MSCC and Baikal-T1 will be a part of the platform driver code, we
  have to preserve the MODEL_MASK macro to use it to filter the model
  flags during the IP-specific quirks activation.
