Gustavo A. R. Silva 54498e8070 i2c: altera: Fix potential integer overflow 
Factor out 100 from the equation and do 32-bit arithmetic (3 * clk_mhz / 10)
instead of 64-bit.

Notice that clk_mhz is MHz, so the multiplication will never wrap 32 bits
and there is no need for div_u64().

Addresses-Coverity: 1458369 ("Unintentional integer overflow")
Fixes: 0560ad5762 ("i2c: altera: Add Altera I2C Controller driver")
