It is necessary to clear MC13892_SWITCHERS0_SWxHI bit when set voltage to the
voltage range from 1100000 to 1375000. Leaving MC13892_SWITCHERS0_SWxHI bit
untouched may result in wrong voltage setting.

For example, currently switch voltage from 1400000 to 1300000 will set the
voltage to 1800000 because the HI bit is still set.

It's safe to call regulator_unregister() with NULL, thus remove the NULL test
before regulator_unregister() calls.

This patch adds a warning about incorrect regulators instead of
printing the names of non-information message about the wrong amount.

Ensure to unregister all regulators before return error in probe().

The regulator register order depends on the regulator ID pass to
ab3100_regulator_register() function. Thus we need to scan ab3100_regulator_desc
and find the index of successfully registered regulators, or alternatively just
call ab3100_regulators_remove() to unregister all registered regulators.

Since current code uses a static ab3100_regulators table, explicitly set
reg->rdev = NULL after regulator_unregister() call to ensure calling
ab3100_regulators_remove() in the unwind path always work.

Also move ab3100_regulators_remove() to avoid forward declaration.
