hw/i2c/versatile_i2c: Rename versatile_i2c -> arm_sbcon_i2c

This device model started with the Versatile board, named
TYPE_VERSATILE_I2C, then ended up renamed TYPE_ARM_SBCON_I2C
as per the official "ARM SBCon two-wire serial bus interface"
description from:
https://developer.arm.com/documentation/dui0440/b/programmer-s-reference/two-wire-serial-bus-interface--sbcon

Use the latter name as a better description.
