i2c: designware: Discard Cherry Trail model flag
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. Let's remove it. Since MODEL_MSCC_OCELOT is the only model-flag left, redefine it to be 0x100 so setting a very first bit in the MODEL_MASK bits range.
