Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema. This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.
Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.
While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

BMC156 is very smilar to BMC150, but it has 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.
In this case, it does not make sense if the first interrupt pin is
treated as INT1 (since that pin does not exist). Add a note to the
bindings that the first interrupt pin is treated as INT2 for BMC156.

In Linux the bma180 and bmc150-accel driver cover fairly similar chips
from Bosch (just with minor register differences). For the DT schema,
this does not make any difference: They both represent I2C/SPI devices,
have one or two interrupts plus a vdd/vddio-supply.
This means there is no need to duplicate the schema, we can just
document the compatibles for both drivers in a single DT schema.

Bosch accelerometers similar to BMA255 are initially configured to
emit an active-high interrupt signal. This is currently not re-configured
in the bmc150-accel driver so the interrupt should most certainly be
IRQ_TYPE_EDGE_RISING (or potentially IRQ_TYPE_LEVEL_HIGH).
(Unless there is some kind of inverter installed on the board...)
At the moment the bmc150-accel driver forcefully requests the IRQ
using IRQF_TRIGGER_RISING, which means that the IRQ type is currently
ignored in all existing device trees.

BMA253 has two interrupt pins (INT1 and INT2) that can be configured
independently. At the moment the bmc150-accel driver does not make use
of them but it might be able to in the future, so it's useful to already
specify all available interrupts in the device tree.
Set maxItems: 2 for interrupts to allow specifying a second one.
This is necessary as preparation to move the bosch,bma254 compatible
from bosch,bma180.yaml to bosch,bma255.yaml since bma180 allows two
interrupts, but BMA254 is better supported by the bmc150-accel driver.

The bmc150-accel-i2c.c driver has an "_accel" suffix for the
compatibles of BMC150 and BMI055. This is necessary because BMC150
contains both accelerometer (bosch,bmc150_accel) and magnetometer
(bosch,bmc150_magn) and therefore "bosch,bmc150" would be ambiguous.
However, the binding documentation suggests using "bosch,bmc150".
Add the "_accel" suffix for BMC150 and BMI055 so the binding docs
match what is expected by the driver.
