[PATCH] clk:sophgo: Remove uninitialized variable for CV1800 PLL

[Ragavendra <ragavendra.bn@gmail.com>]

Updating the detected value to 0 in the ipll_find_rate and removing it
from the method parameters as it does not depend on external input.
Updating the calls to ipll_find_rate as well and removing the u32 val
variable from ipll_determine_rate.

Fixes: 80fd61ec4612 ("clk: sophgo: Add clock support for CV1800 SoC")
