The AD5625/AD5645/AD5665 are a family of 4 channel DACs with 12-bit, 14-bit
and 16-bit precision respectively. The devices come in 3 flavors in terms
of built-in reference, either no built-in reference, built-in 1.25V
reference or built-in 2.5V reference.

The AD5627/AD5647/AD5667 are similar to the AD5625/AD5645/AD5665 except
that they have 2 instead of 4 channels.

While these new devices are mostly register map compatible with the
existing devices support by the driver some offsets and register addresses
have been shuffled around. To accommodate this introduce a new register map
layout. For the lack of a better name we will just call it version 2.

Adjust the DECLARE_AD5064_CHANNELS() macro to accept a new
ext_info parameter. This allows to use different power down
modes per DAC. (e.g. DAC only support 90kohm to ground)

Add the chip_info parameter "powerdown_ltc". This parameter is
used in the ad5064_sync_powerdown_mode() function to handle the
power down command for LTC diffently. For those devices the

wilc_set_machw_change_vir_if is not used anymore since we use one unified

Building wilc1000 with clang currently fails in the staging-next branch:

drivers/staging/wilc1000/wilc_spi.c:123:34: warning: tentative definition of variable with internal linkage has incomplete non-array type 'const struct wilc1000_ops' [-Wtentative-definition-incomplete-type]
static const struct wilc1000_ops wilc1000_spi_ops;

The reason is that wilc1000_ops was left behind after a recent cleanup,
and is completely unused and also uninitialized and const and has an
incomplete type.

Removing the variable is obviously correct, and gets rid of the warning.
