regulator: max77650: use vsel_step
Use the new vsel_step field in the regulator description to instruct
the regulator API on the required voltage ramping. Switch to using the
generic regmap helpers for voltage setting and remove the old set_voltage
callback that handcoded the selector stepping.

regulator: max77650: add MODULE_ALIAS()
Define a MODULE_ALIAS() in the regulator sub-driver for max77650 so that
the appropriate module gets loaded together with the core mfd driver.

regulator: max77650: Move max77651_SBB1_desc's declaration down
Clang warns:

drivers/regulator/max77650-regulator.c:32:39: warning: tentative
definition of variable with internal linkage has incomplete non-array
type 'struct max77650_regulator_desc'
[-Wtentative-definition-incomplete-type]

              ^
1 warning generated.

Move max77651_SBB1_desc's declaration below max77650_regulator_desc's
definition so this warning does not happen.

regulator: max77650: Convert MAX77651 SBB1 to pickable linear range
The pickable linear range is suitable for The MAX77651 SBB1.
According to MAX77651 TV_SBB1 Code Table:
Use BIT[1:0] as range selectors.
Use BIT[5:2] as selectors for each linear range.

The MAX77651 SBB1 supports up to selector 57, selector 58 ~ 63 are RSVD,
thus set n_voltage to 58.
