Subject: [PATCH v3 06/11] i2c: riic: Define individual arrays to describe the register offsets

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Define individual arrays to describe the register offsets. In this way
we can describe different IP variants that share the same register offsets
but have differences in other characteristics. Commit prepares for the
addition of fast mode plus.
