The I2C Master Hub is a stripped down version of the GENI Serial Engine QUP Wrapper Controller but only supporting I2C serial engines without DMA support. Document the I2C Serial Engine variant used within the I2C Master Hub Wrapper. This serial engine variant lacks DMA support, requires a core clock, and since DMA support is lacking the memory interconnect path isn't needed.
