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.

Use spi_get_device_match_data() helper to simplify a bit the driver.

'max5522_channels' was not declared. Should it be static?
This variable is only used in one file so it should be static.

Add initial support for DAC max5522.
Tested writing DAC A and B with some values,
from 0 to 1023, measured output voltages, driver works properly.
Additions for max5523/24/25 will follow.
