Some BOSC0200 acpi_device-s describe two accelerometers in a single ACPI
device. Normally we would handle this by letting the special
drivers/platform/x86/i2c-multi-instantiate.c driver handle the BOSC0200
ACPI id and let it instantiate 2 bmc150_accel type i2c_client-s for us.
But doing so changes the modalias for the first accelerometer
(which is already supported and used on many devices) from
acpi:BOSC0200 to i2c:bmc150_accel. The modalias is not only used
to load the driver, but is also used by hwdb matches in
/lib/udev/hwdb.d/60-sensor.hwdb which provide a mountmatrix to
userspace by setting the ACCEL_MOUNT_MATRIX udev property.
Switching the handling of the BOSC0200 over to i2c-multi-instantiate.c
will break the hwdb matches causing the ACCEL_MOUNT_MATRIX udev prop
to no longer be set. So switching over to i2c-multi-instantiate.c is
not an option.
Changes by Hans de Goede:
-Add explanation to the commit message why i2c-multi-instantiate.c
cannot be used
-Also set the dev_name, fwnode and irq i2c_board_info struct members
for the 2nd client

This adds support for the BMA222 version of this sensor,
found in for example the Samsung GT-I9070 mobile phone.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
The I2C device ID table entries have the .driver_data field set, but they
are not used in the driver so weren't set in the OF device table entries.

Add support for the BOSC0200 ACPI device id used on some x86 tablets.
note driver_data is not set to a specific model, driver_data is not
used anyways (instead detection is done on the chip_id reg) and the
2 tablets with a BOSC0200 ACPI device id I've have 2 different chips,
one has a BMA250E, the other a BMA222E.

bmc150_i2c_regmap_conf is defined three times (in bmc150-accel-core.c,
bmc150-accel-i2c.c and and bmc150-accel-spi.c), although the
definition is the same.
Use one common definition for bmc150_i2c_regmap_conf in all
included files.
