Added triggered buffer mode support for the STK8312 accelerometer.
Additional changes:
- set_mode now sets operation mode directly, no longer masking
the register's previous value
- read_accel now returns raw acceleration data instead of the
sign_extend32 value
- read_raw will now enable/disable the sensor with each reading

In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.

This patch changes the semantics of non-blocking reads so that a
hardware fifo flush is triggered if the available data in the device
buffer is less then the requested size.
This allows userspace to accurately generate hardware fifo flushes, by
doing a non-blocking read with a size greater then the sum of the
device buffer and hardware fifo size.

The ADC is typically shared with remote CPUs not running Linux.
However, there is only one register to power-up/power-down. Remote CPUs
aren't able to power-up the ADC, and rely in Linux doing it instead.
This commit uses the adc-reserved-channels devicetree property to
distinguish shared usage. In this case, the ADC is powered up at
probe time.
If the ADC is used only by the CPU running Linux, power-up/down
at runtime, only when neeeded.
