CPLD update: Add individual IO_UPDATE, PROFILE, OSK, DRG and ATT capabilities

[newell]

This PR adds:

1. Decoupling for the individual DDS channels.
2. Individual DDS Channel control of:
   • PROFILE
   • IO_UPDATE
   • OSK
   • DRCTRL
   • DRHOLD
   • ATT_EN

which allows OSK, DRG and other capabilities to ARTIQ.

This helps address many of the items in:

#7

For ARTIQ coredevice driver code to use these changes see:

I have tested with with v1.4 hardware but it should work with newer revisions as well. You will need updated ARTIQ drivers in order to use this code. See m-labs/artiq#2657

Thanks a lot, @newell ! A few quick questions:

• Can I still connect 6 Urukuls to 1 Kasli (SoC)? If not, how many Urukuls can I maximally connect to 1 Kasli (SoC)?
• Do I lose any existing hardware capability? For instance, are the RF switches slower compared to before? (Are they moved from TTL to a serial bus or smth like that?)
• Has M-Labs already given you a time estimate of how soon your PR will be integrated into main-line Artiq? (weeks / months / longer?)

These changes don't modify Kasli connection capabilities.

• Do I lose any existing hardware capability? For instance, are the RF switches slower compared to before? (Are they moved from TTL to a serial bus or smth like that?)

RF switches weren't modified, you can check the diff.

• Has M-Labs already given you a time estimate of how soon your PR will be integrated into main-line Artiq? (weeks / months / longer?)

This would be a question for @sbourdeauducq
