Subject: [PATCH 4/4] ASoC: cs42l42: Remove redundant pll_divout member

Now that struct cs42l42_private has pll_config, the current PLL
configuration can be looked up directly in pll_ratio_table. This
makes the pll_divout member of cs42l42_private redundant since it
was only a copy of the value from pll_ratio_table.
