The struct of_regulator_match rmatch[] is declared as a non-static local
variable so the structure members are not auto-initialized.
Initialize the array at declaration time to avoid the structure members
values to be indeterminate and have sane defaults instead.

This patch makes the regulator description macro take minimum and
steps voltage as parameter. In this way many repeated macros can be
removed. Now these macros are repeated only if the the LDO/BUCK ctrl
registers have non-linear positions. The good thing is these ctrl registers
are mostly linear so they are not passed as parameters.
This patch reduces the code size and also allow easy addition of more
s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.

This is a cleanup patch and moves min/step voltages in a common samsung
header file so that they can be used by other s2mpxxx PMIC drivers. Only
few required macros are added currently and others can be added if needed.

S2MPA01 supports enabling/disabling ramp delay only for buck[1234].
Other bucks have ramp delay enabled always.
However the bit shift for enabling buck4 ramp delay in register is equal
to 0. When ramp delay was set for the bucks unsupporting enable/disable
(buck[56789] and buck10), the ramp delay for buck4 was also enabled.
Fixes: f7b1a8dc1c1c ("regulator: s2mpa01: Don't check enable_shift before setting enable ramp rate")

Fix the register for ramp delay of buck1 regulator. Buck1 and buck6
share the field (offset 4) in ramp delay register S2MPA01_REG_RAMP2.
The driver used the same register and field for ramp delay of buck3 and
buck1. This lead to updating of ramp delay of buck3 when setting buck1
and actually the ramp delay of buck1 was never set.

Current code misses updating the register when enable_shift is 0.
e.g. S2MPA01_BUCK4_RAMP_EN_SHIFT is 0.
