[PATCH 3/7] ram: renesas: dbsc5: Fix JS1 index calculation

[Marek Vasut]

The JS1 index is calculated correctly, but the limiter cannot
be the max() function because the index should be lower than
JS1_USABLEC_SPEC_HI and the max() function would unconditionally
override the JS1 index to JS1_USABLEC_SPEC_HI. Use clamp() to
limit the JS1 index instead.
