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.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba6 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:
SPI driver sca3300 has no spi_device_id for murata,scl3300
Add spi_device_id entries to silence the warning, and ensure driver
module autoloading works.

After added inclination angle channels, the trigger buffer size is
insufficient. Extend the buffer size from 16 to 32 bytes, and change
the trigger buffer from the struct to a u8 array to adapt the sensor
with/without inclination angles output.
New trigger buffer data:
- SCA3300: 3 accel channels, temp, and timestamp.
- SCL3300: 3 accel channels, temp, 3 incli channels, and timestamp.
Readjustment the scan index to make it consistent with the buffer data.

Different from SCA3300, SCL3300 can output inclination angles.
Angles are formed from acceleration with following equations:
ANG_X = atan2(accx , sqrt(pow(accy , 2) + pow(accz , 2)))
ANG_Y = atan2(accy , sqrt(pow(accx , 2) + pow(accz , 2)))
ANG_Z = atan2(accz , sqrt(pow(accx , 2) + pow(accy , 2)))
The commit adds the output of the raw value, scale
and scale_available of angles.
New interfaces:
in_incli_scale
in_incli_scale_available
in_incli_x_raw
in_incli_y_raw
in_incli_z_raw
Data converted by application of scale to degrees.
