Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro
USB Interface Controller), and flash and RGB LED controllers.
S2MU005's interrupt registers divided into three domains, each for the
charger, flash LEDs, and the MUIC, packed into a single regmap IRQ chip
construct.
In devices other than S2MPG1X, the revision can be retrieved from the
first register of the PMIC regmap. In S2MU005 however, the location is
in offset 0x73. Introduce a switch-case block to allow selecting the
REG_ID register. S2MU005 also has a field mask for the revision. Apply
it using FIELD_GET() and get the extracted value.
Add initial support for S2MU005 in the PMIC driver, along with its three
interrupt chips, and support for allowing to fetch revision based on the
device variant.

Add myself as module author, so people know whom to complain to about
after the recent updates.

Now that sec-i2c doesn't match device type by pointer casting anymore,
we can switch the device type from unsigned long to int easily.
This saves a few bytes in struct sec_pmic_dev due to member alignment.

Instead of a large open-coded switch statement, just add both regmap
config and device type to the OF match data. This allows us to have all
related information in one place, and avoids a long switch() statement.

When support for PMICs without compatibles was removed in
commit f736d2c0caa8 ("mfd: sec: Remove PMICs without compatibles"),
sec_regmap_config effectively became an orphan, because S5M8763X was
the only user left of it before removal, using the default: case of the
switch statement.
When s2dos05 and s2mpu05 support was added in commit bf231e5febcf
("mfd: sec-core: Add support for the Samsung s2dos05") and commit
ed33479b7beb ("mfd: sec: Add support for S2MPU05 PMIC"), they ended up
using that orphaned regmap_config in a non-obvious way due to the
default: case of the device type switch matching statement taking
effect again.
To make things more obvious, and to help the reader of this code while
reasoning about what the intention might be here, and to ensure future
additions to support new devices in this driver don't forget to add a
regmap config, add an explicit regmap config for these two devices, and
completely remove the generic regmap config as it becomes an orphan
again that shouldn't be used by any device.
Note that this commit doesn't fix the issue that s2dos05_regmap_config
ands2mpu05_regmap_config really are incomplete, but I have no
documentation on them.

dev_err_probe() exists to simplify code and harmonise error messages,
there's no reason not to use it here.
While at it, harmonise some error messages.

Sort struct of_device_id entries and the device type switch in _probe()
alphabetically, which makes it easier to find the right place where to
insert new entries in the future.

As a preparation for adding support for Samsung's S2MPG10, which is
connected via SPEEDY / ACPM rather than I2C, split out (move) all
I2C-specific driver code into its own kernel module, sec-i2c, and
make the existing sec-core module be just the transport-agnostic core
driver kernel module.
At the same time, update all defconfigs that reference the old kconfig
symbol name.
While at it, also update file header comments and module description(s)
to drop references to 'mfd', and update comments to be C-style, not
C++.
