clk: sophgo: avoid open-coded 64-bit division

On 32-bit architectures, the 64-bit division leads to a link failure:

arm-linux-gnueabi-ld: drivers/clk/sophgo/clk-cv18xx-pll.o: in function `fpll_calc_rate':
clk-cv18xx-pll.c:(.text.fpll_calc_rate+0x26): undefined reference to `__aeabi_uldivmod'

This one is not called in a fast path, and there is already another div_u64()
variant used in the same function, so convert it to div64_u64_rem().
