clk: samsung: Keep CPU clock chip specific data in a dedicated struct

Keep chip specific data in the data structure, don't mix it with code.
It makes it easier to add more chip specific data further. Having all
chip specific data in the table eliminates possible code bloat when
adding more rate handlers for new chips, and also makes it possible to
keep some other chip related data in that array.

No functional change.
