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.

Apply the following coding style changes as indicated by checkpatch.pl in
strict mode:
  - Please don't use multiple blank lines
  - braces {} should be used on all arms of this statement (if/else)
  - Alignment should match open parenthesis
  - Please don't use multiple blank lines
  - Blank lines aren't necessary after an open brace '{'
  - Missing a blank line after declarations
  - No space is necessary after a cast

Also wrap/consolidate error messages to fit 80 characters per line and
rework a comment.

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.
