soc: qcom: geni-se: add support for I2C Master Hub wrapper variant

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.

Add the clock list for the I2C Master Hub variant to a new desc struct
then pass it through the I2C Master Hub compatible match data.
