media: i2c: Use div64_ul() for u64-by-unsigned-long divide
div_u64() does a 64-by-32 division, while the divisor max2175.xtal_freq
is unsigned long, thus 64-bit on 64-bit platforms. Hence the proper
function to call is div64_ul().
Note that this change does not have any functional impact, as the
crystal frequency must be much lower than the 32-bit limit anyway.
On 32-bit platforms, the generated code is the same. But at least on
arm64, this saves an AND-instruction to truncate xtal_freq to 32-bit.
