This will be used by the kernel GPIO driver to synchronize
with the CF when accessing GPIO shared with FSI.

Break sends a break command. It has 16000 recovery cycles as
per the existing GPIO based driver, though that might be
unnecessary in practice.
"idle clocks" sends up to 255 clocks with data line held high,
and can be used to flush things out for example after changing
the send delay, or before sending a DPOLL command as some CFAMs
seem to require extra clocks there.
