Hacks

Slightly less stubby than the memorybus hacks

Makes log less noisy

With a hack to constantly empty it so that we don't hang

Hopefully to make my high-level hacks less hacky... and not in the core

Causes more sync problems than it solves

Otherwise every read/write is going to happen on the first cycle

Slightly more work as commands/data go through the same program

There are pullups on the board and the ps sdk doesn't enable the internal ones (due to a bug)

Removes a picosystem-sdk check

Default to values used by the picosystem sdk as we don't handle the writes from there yet (no SPI support)

Should be the last user of the flag

Leave enough to override board type and tell the user to do that instead

Will need this for some more PIO hacks

Really need to be a lot more strict about syncing bus masters... but this is an improvement

Definitely can't be stalled if the FIFO isn't empty

Sometimes we get out of sync and the FIFO is stuck full...
