All 4 patches could have been squashed in a single patch as they do the
same thing, but I'm fine either way:

I'm happy to squash them if that's the preference? Krzysztof? Cheers, Andre'

The pinctrl instances hsi1, gsactrl, and gsacore need a clock for register access to work. Since we haven't implemented the relevant CMUs for the clocks required by these instances just add empty clocks for now so as to make the DT pass the validation checks. Once the clocks are implmented in the gs101 clock driver, these should be updated then.
