Now that there are no longer any users of regmap.h in headers, let's
switch all users in the source files to linux/regmap.h.
That way, the only users of regmap.h whether directly or indirectly will
be out-of-tree code, which will fail with an error if they are dependent
on the old semantics of regmap_bulk_read and regmap_bulk_write.
After a transitory period, we can then drop regmap.h.

Add .supply_name to the regulator descriptors, otherwise the supplies
are never enabled.

To get the current voltage from the regulators the .get_voltage_sel
callback is needed. Initialize it to the correct function.

Syncing device trees with Linux upstream can lead to breakage, when
the device trees are switched to newer bindings, which are not yet
supported in barebox. To make it easier to spot such issues, we want to
start applying some heuristics to flag possibly problematic DT changes.
One step towards being able to do that is to know what nodes barebox
actually consumes. Most of the nodes have a compatible entry, which is
matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE
point at it for future extraction.

The '_d' suffix was originally meant to distinguish barebox struct
names from Linux struct names. struct driver doesn't exist in Linux,
so we can rename it and remove the meaningless suffix.

The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

Linux struct device has the member of_node for the device_node pointer.
Rename this in barebox accordingly to minimize the necessary changes
when porting Linux code. This was done with the semantic patch:
@@ struct device_d E; @@
- E.device_node
+ E.of_node
@@ struct device_d *E; @@
- E->device_node
+ E->of_node
Plus some manual adjustments.

Drop the local reference for each driver since the regulator_dev can
handle this now. Attention: The pfuze is out of scope since this driver
is not really a regulator driver.
While on it fix a few minor style issues on the bcm2835 driver too.

It is useful to know the physical device a regulator_dev belongs to.
This is at least needed for the new deep-probe mechanism. It is also
useful for a few regulator drivers to drop their own device_d reference.

The dts regulators subnode can be incomplete e.g. if the pre-programmed
values are valid and shouldn't be changed. Missing regulator nodes are
indicated by "of_regulator_match->of_node == NULL". Take missing
regulators into account and register only existing ones.

This commit imports the Linux v5.3 state of the driver. This allows us
to regulate at least the v3v3 voltage rail used by the DK1 and DK2
Ethernet PHY and SD-Card. Eventually, this driver should be used by the
USB host driver to supply the vbus voltage as well.
