Currently, if one of the factors isn't present, bit 0 gets always set to 1. For example, A83T has NMP PLLs modelled as NKMP PLL without K. Since K is not specified, it's offset, width and shift is 0. Driver assumes that lowest value possible is 1, otherwise we would get division by 0. That situation causes that bit 0 is always set, which may change wanted clock rate. Fix that by masking every factor according to it's specified width. Factors with width set to 0 won't have any influence to final register value. Signed-off-by: Jernej Skrabec <redacted>
