regulator: Updates for v5.4 

A small update for the regualtor API for this cycle, some small fixes
 and a bunch of new devices but none of them very big.  The most stand
 out thing is the regulator-fixed-clock driver which is for regulators
 where the enable control is done by using a clock instead of a GPIO or
 register write, a novel hardware design that had not previously come up.
 
  - Added a keyword pattern for regulator_get_optional() since usage of
    that API generally needs extra review.
  - Operating mode and suspend state support for act8865.
  - New device support for Active Semiconductor ACT8600 chargers,
    Mediatek MT6358, Qualcomm SM8150, regulator-fixed-clock, and
    Synoptics SY20276, SY20278 and SY8824E.

MediaTek MT6358 Regulator
All voltage regulators provided by the MT6358 PMIC are described as the
subnodes of the MT6358 regulators node. Each regulator is named according
to its regulator type, buck_<name> and ldo_<name>. The definition for each
of these nodes is defined using the standard binding for regulators at
Documentation/devicetree/bindings/regulator/regulator.txt.
The valid names for regulators are::
BUCK:
buck_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
buck_vs2, buck_vmodem, buck_vs1
LDO:
