regulator: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 5.4 and 5.10

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 5.4 but did exist in Linux 5.10.

regulator: Add a routine to set the current limit for QCOM PMIC VBUS

Add hooks to regulator_get_current_limit_regmap() and
regulator_set_current_limit_regmap() with an accompanying map of amperages.

This lets us use the existing helper functions to map requested current
settings to register bit-map/indicies.

This change is required to elevate the default 2 Amps set by the bootloader
to 3 Amps or indeed to constrain the value lower as the system design may
dictate.

The valid range is 500 mA to 3 A in increments of 500 mA.

regulator: fix null pointer check on regmap

The null pointer check on regmap that checks for a dev_get_regmap failure
is currently returning -ENOENT if the regmap succeeded. Fix this by adding
in the missing ! operator.

regulator: Add support for QCOM PMIC VBUS booster

Some Qualcomm PMICs have the capability to source the VBUS output to
connected peripherals. This driver will register a regulator to the
regulator list to enable or disable this source by an external driver.
