Don't store pointers to regulator_dev returned by
devm_regulator_register() in allocated memory in state container. They
aren't used anywhere outside of max77693_pmic_probe() function.
This change allows removing completely the 'struct max77693_pmic_dev'
state container as none of its fields are used outside of probe.

This patch extends the regulator helpers to account for device that use
multiple bits for control when using regmap enable/disable/bypass ops.
The actual regulator helpers wrongly assume that the regulator control
is always performed using single bits, using in the regulator_desc
struct only two parameters *_reg and *_mask defining register and mask
for control.
This patch extends this struct and introduces the helpers to take into
account devices where control is performed using multiple bits and
specific multi-bit values are used for enabling/disabling/bypassing the
regulator.

A couple of fixes here which ensure that regulators using the core
support for GPIO enables work in all cases by ensuring that helpers are
used consistently rather than open coding in places and hence not having
GPIO support in some of them.

Remove __initconst from regulator_desc array because this array is used
during probe and s2mps11_pmic_probe() is not in __init section. However
still select the number of supported regulators according to device ID
so the driver will be ready for adding support for S2MPS14 device.

Add __initconst to 'regulator_desc' array with supported regulators.
During probe choose how many and which regulators will be supported
according to device ID. Then copy the 'regulator_desc' array to
allocated memory so the regulator core can use it.
Additionally allocate array of of_regulator_match() dynamically (based
on number of regulators) instead of allocation on the stack.
This is needed for supporting different devices in s2mps11
driver and actually prepares the regulator driver for supporting the
S2MPS14 device.
Code for supporting the S2MPS14 device will add its own array of
'regulator_desc' (also marked as __initconst). This way memory footprint
of the driver will be reduced (approximately 'regulators_desc' array for
S2MPS11 occupies 5 kB on 32-bit ARM, for S2MPS14 will occupy 3 kB).

There are many places where ops->disable is called directly. Instead we
should use _regulator_do_disable() which also handles gpio regulators.
To be able to use the wrapper function from _regulator_force_disable(),
I moved the _notifier_call_chain() call from _regulator_do_disable() to
_regulator_disable(). This way, _regulator_force_disable() can use
different flags for _notifier_call_chain() without calling it twice.

There are some direct ops->enable in the regulator core driver. This is
a potential issue as the function _regulator_do_enable() handles gpio
regulators and the normal ops->enable calls. These gpio regulators are
simply ignored when ops->enable is called directly.
One possible bug is that boot-on and always-on gpio regulators are not
enabled on registration.
This patch replaces all ops->enable calls by _regulator_do_enable.
