Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.
For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

In general the complexity of avoiding maybe unused variable warnings is
not worth dealing with for the small amount of data saved. In thie
case, the i2c driver does include some other code under a CONFIG_ACPI
guard but remove the ACPI_PTR() usage anyway to bring keep it inline
with the spi driver.
Drop include of linux/acpi.h in the spi driver that doesn't need
it as struct acpi_device_id is defined in mod_devicetable.h which
is already included.

To avoid unnecessary pollution of the global symbol namespace move the
driver core exports into their own namespace and import that into the two
bus modules.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Up to now bmc150_accel_core_remove() returns zero unconditionally. Make
it return void instead which makes it easier to see in the callers that
there is no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.

BMC156 is another accelerometer that works just fine with the bmc150-accel
driver. It's very similar to BMC150 (also a accelerometer + magnetometer
combo) but with only one accelerometer interrupt pin. It would make sense
if only INT1 was exposed but someone at Bosch decided to only have an
INT2 pin.
Try to deal with this by making use of the INT2 support introduced
in the previous commit and force using INT2 for BMC156. To detect
that we need to bring up a simplified version of the previous type IDs.
Note that unlike the type IDs removed in commit c06a6aba6835
("iio: accel: bmc150: Drop misleading/duplicate chip identifiers")
here I only add one for the special case of BMC156. Everything else
still happens by reading the CHIP_ID register since the chip type
information often is not accurate in ACPI tables.

BMA253 is mostly like BMA255 and has exactly the same register layout
as used by the bmc150-accel driver as far I can tell. Making it work
is as simple as adding new device IDs for it since it has the same
chip_id = 0xFA (250) as BMA255 and others.

Right now all the device IDs are listed in seemingly random order,
make this consistent by ordering those alphabetically. Also, order
bmc150_accel_chip_info_tbl by chip ID for the same reason.

Commit 0ad4bf370176 ("iio:accel:bmc150-accel: Use the chip ID to detect
sensor variant") stopped using the I2C/ACPI match data to look up the
bmc150_accel_chip_info. However, the bmc150_accel_chip_info_tbl remained
as-is, with multiple entries with the same chip_id (e.g. 0xFA for
BMC150/BMI055/BMA255). This is redundant now because actually the driver
will always select the first entry with a matching chip_id.
So even if a device probes e.g. with BMA0255 it will end up using the
chip_info for BMC150. And in general that's fine for now, the entries
for BMC150/BMI055/BMA255 were exactly the same anyway (except for the
name, which is replaced with the more accurate one later).
But in this case it's misleading because it suggests that one should
add even more entries with the same chip_id when adding support for
new variants. Let's make that more clear by removing the enum with
the chip identifiers entirely and instead have only one entry per
chip_id.
Note that we may need to bring back some mechanism to differentiate
between different chips with the same chip_id in the future.
For example, BMA250 (currently supported by the bma180 driver) has the
same chip_id = 0x03 as BMA222 even though they have different channel
sizes (8 bits vs 10 bits). But in any case, that mechanism would
need to look quite different from what we have right now.
