[PATCH v2 10/12] i2c: designware: Discard Cherry Trail model flag

2020-05-10T09:51:11Z

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.

By doing so we get rid from the last DW APB I2C IP-core model flag, so we
can remove the MODEL_MASK macro too.
