clk: k210: remove an implicit 64-bit division
The K210 clock driver depends on SOC_CANAAN, which is only selectable
when !MMU on RISC-V. !MMU is not possible on 32-bit yet, but patches
have been sent for its enabling. The kernel test robot reported this
implicit 64-bit division there.
Replace the implicit division with an explicit one.
