Could you add link-frequencies here, too?

This sensor is only used for the time being (as far as I know) on the
the stm32mp135f-dk board which can well handle the 3 link-frequencies.
(some other usages exist, however in parallel mode, which this driver
doesn't support yet).
I was hoping to only add the link-frequencies check when it becomes
necessary to use it on another board.
Do that make sense ?

Alain
