crypto: rockchip - Check for clocks numbers and their frequencies

Add the number of clocks needed for each compatible.
Rockchip's datasheet give maximum frequencies for some clocks, so add
checks for verifying they are within limits. Let's start with rk3288 for
clock frequency check, other will came later.
