clk: clocking-wizard: fix integer overflow in rate calculation
When using driver on Zynq-7000 (32-bit) determine_rate calculation
overflows. For instance requesting 32MHz with 100MHz parent clock
results in 100000000*(4*1000+0) 32-bit multiplication.
Replace the expression with mult_frac which is already used in
clk_wzrd_recalc_ratef.
