iio: refactor info mask and ext_info attribute creation.
Introduce an enum to specify whether the attribute is separate or
shared.
Factor out the bitmap handling for loop into a separate function.
Tidy up error handling and add a NULL assignment to squish a false
positive warning from GCC.
Change ext_info shared type from boolean to enum and update in all
drivers.

iio:ad5064: Fix off by one in DAC value range check
The DAC value range check allows values one larger than the maximum value, which

iio:ad5064: Fix address of the second channel for ad5065/ad5045/ad5025
The ad5065, ad5045, ad5025 use address '3' for the second channel, so they need
their own channel spec.
Note that ad5064_sync_powerdown_mode() also needs to be slightly updated since
it was relying on the fact that chan->address always equaled chan->channel.

Drivers: iio: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

iio: ad5064: Move bus write callbacks to #if protected sections
Move the SPI and I2C specific write callbacks to the respective
"#if IS_ENABLED(CONFIG_SPI_MASTER)" and "#if IS_ENABLED(CONFIG_I2C)"
protected sections of the code.
This fixes the following warning which occurs if CONFIG_I2C is not set:
drivers/iio/dac/ad5064.c: In function ‘ad5064_i2c_write’:
drivers/iio/dac/ad5064.c:132: error: implicit declaration of function ‘i2c_master_send’
And the follwing warning which occurs when CONFIG_SPI_MASTER is not set:
drivers/iio/dac/ad5064.c:137: warning: ‘ad5064_spi_write’ defined but not used

iio:dac:ad5064: Add support for the ad5629r and ad5669r
The ad5629r and ad5669r are the I2C variants of the ad5628 and ad5668. Since the
ad5064 driver currently only supports SPI based devices the major part of this
patch focuses on adding support for I2C based devices. Adding support for the
actual parts boils down to adding entries for them to the device id table.

staging:iio: Move DAC drivers out of staging
The IIO DAC drivers are in a reasonably good shape. They all make use of channel
spec and non of them provides non-documented sysfs attributes. Code style should
be OK as well, both checkpatch and coccicheck only report trivial issues.
So lets move the whole folder out of staging.
