This is a complete rewrite of the AD9832/35 driver.
Purpose was to move this driver to the recently
created API for such devices.
Changes since V1:
IIO: DDS: AD9832 / AD9835 driver: Apply review feedback
Save a few bytes, use union for data allocated for spi buffers.
Remove use of device IDs.
Fix comments.
Make master clock mclk always type unsigned long.

This patch adds a new trigger that can be invoked by writing
the sysfs file: trigger_now. This approach can be valuable during
automated testing or in situations, where other trigger methods
are not applicable. For example no RTC or spare GPIOs.
Last but not least we can allow user space applications to produce triggers.
IIO: TRIGGER: Apply review feedback by Greg Kroah-Hartman
Changes since v1:
Add sysfs documentation.
Change license notice.
Add module alias.
Add more Kconfig help text

This is a static checker patch and I don't have this hardware.
This code is unusual because while I've often seen a double lock, this
is the first time I've seen code that takes a lock 11 times in a row. I
feel like I must have missed something. But I've looked very carefully
I don't see any way the original code is correct. Does spi_sync()
somehow release the lock in a way that I can't see? Even if it does,
the locking would still be wrong.
