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

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.

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.
