Here and below, delete local copies of the wait routines, replace calls to local wait_100ms with cpu.wait_100ms.

Move the wait_tens implementation below out of the nested namespace so it can be cleanly accessed by all routines in this module.

Extracted 2x-core-aware timed sleep* implementations from iec.asm, renamed to wait*, double-checked & tightened up the timings.
All waits are now 2x-core-compatible Signed-off-by: Aleksey Gurtovoy <aleks@wildbitscomputing.com>
