In order to improve power consumption ls102x allows to disable peripherals
that are not in use.
This patch follows SELI8 HW design description and disables peripherals
that are not in use in our designs, the same configuration is applicable
and for EXPU1.

This patch uses available hwconfig option for updating ls102x device
disable configuration.
