regulator: Updates for v6.2

Browse Source 
Quite a quiet release for regulator, the diffstat is dominated by the
 I2C migration to probe_new() and the newly added MT6357 driver.  We've
 just one framework addition and the rest is all new device support,
 fixes and cleanups.
 
 The framework addition is an API for requesting all regulators defined
 in DT, this isn't great practice but has reasonable applications when
 there is generic code handling devices on buses where the bus
 specification doesn't include power.  The immediate application is MDIO
 but I believe there's others, it's another API that'll need an eye
 keeping on it for undesirable usage.
 
  - An API for requesting all regulators defined in DT.
  - Conversion of lots of drivers to the I2C probe_new() API.
  - Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and
    Richtek RT6190.
 
 There's a cross tree merge with the I2C tree in order to use the new
 i2c_client_get_device_id() helper in the conversions to probe_new().

maintainers:
- ChiYuan Huang <cy_huang@richtek.com>
description: |
The RT6190 is 4-Switch BuckBoost controller designed for converting input
voltage to output voltage that can be equal to, higher or lower than input
voltage. It operates with wide input voltage range from 4.5V to 36V, and
the output voltage can be set from 3V to 36V by external FB pin. It's commonly
used for the application like as BuckBoost bus supply, docking station and USB
power delivery product.
