e6ed90581b regulator: arizona-micsupp: Enable SYSCLK for charge pump
If we are in non-bypass mode then the SYSCLK is required for full charge
pump operation, otherwise we will fall back to bypass mode. Use the DAPM
context exposed by the ASoC driver to manage this.

7f217d36dc regulator: arizona-micsupp: Fix choosing selector in arizona_micsupp_map_voltage
If min_uV is in the range of: 3250001~3269999,
current code uses the equation:
        selector = DIV_ROUND_UP(min_uV - 1700000, 50000);
Then selector will be 32.
Then arizona_micsupp_list_voltage returns -EINVAL for this case which is wrong.

This patch fixes this issue:
If min_uV > 3200000, selector should be ARIZONA_MICSUPP_MAX_SELECTOR.
