To my mind, if a gpio is specified in the board file, yet fails
to be successfully requested, that is an error condidtion and
the driver should not muddle on regardless.
This does mean unwinding the gpios on error. Also the free_gpios
function is reordered so that it is consistent with the request one
(reverse order obviously).
This patch is the category of not technically fixing anything, just
making the driver be more in line with what a reviewer will expect.

The recent reorganization of the sysfs attribute registration had
the side effect of moving iio_device_register after registration of
triggers etc. The side effect of this is that the id hadn't been
allocated by the time of trigger registration. Thus all triggers
based on device got the name <dev_name>-dev0 instead of <dev_name>-devN
where N is the iio device id.
This should also fix the lack of device name for some error messages
that we have been seeing (and I'd been meaning to track down) as
that has now moved earlier as well.

V3 is a straightforward forward port to teh current tree of V2.
Simple fix is to just not cache REG_TEST (offset 8).
Cache doesn't help REG_TEST anyway since we write all 8 bits exactly once
(at resume/init time).
Also fix an "off-by-one" allocation of reg_cache[] array size that
was in the original code before I touched it.
