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.

This patch makes minor structural changes to support specifics
for LTC2617 DAC. This DAC requires different handling of the
power down modes. The configuration to actually support the
DAC will be submitted in a secondary patch.
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
power down command must be addressed to the channel.
