  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.

This adds the I2C Master Hub serial engine compatible along the
specific requirements in a new desc struct passed throug the device
match data.
