[RFC PATCH v2 01/14] hw/i2c/omap_i2c: add a dedicated CONFIG_OMAP_I2C symbol

The OMAP I2C controller model was only buildable as part of the full OMAP1
SoC (CONFIG_OMAP). The same IP is used by the TI K3 family (AM64x and
friends), which shares nothing else with OMAP1.

Give the device its own Kconfig symbol and select it from CONFIG_OMAP, so
that other SoCs can reuse the model without pulling in OMAP1.

No functional change.
