[PATCH v3 17/20] soc: mediatek: mtk-svs: Use ULONG_MAX to compare floor frequency

[AngeloGioacchino Del Regno]

The `freq` variable is of type unsigned long and, even though it does
currently work with u32 because no frequency is higher than U32_MAX,
it is not guaranteed that in the future we will see one.
Initialize the freq variable with ULONG_MAX instead of U32_MAX.
