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.

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.
