I had the same problem and currently only see these two possibilities:

1. Import each constant and assign it in the myhdl code, like this:

from cpumode import CpuMode
cpumode_User = CpuMode.User
...

2. Define the constants as module level constants
and use 'from mymodule import *' in the myhdl code.
