soc: qcom: geni-se: add desc struct to specify clocks from device match data

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.

Prepare support for the I2C Master Hub variant by moving the required
clocks list to a new desc struct then passing it through the compatible
match data.
