Mark Cave-Ayland 366d27796c mac_via: work around underflow in TimeDBRA timing loop in SETUPTIMEK 
The MacOS toolbox ROM calculates the number of branches that can be executed
per millisecond as part of its timer calibration. Since modern hosts are
considerably quicker than original hardware, the negative counter reaches zero
before the calibration completes leading to division by zero later in
CALCULATESLOD.

Instead of trying to fudge the timing loop (which won't work for TimeDBRA/TimeSCCDB
anyhow), use the pattern of access to the VIA1 registers to detect when SETUPTIMEK
has finished executing and write some well-known good timer values to TimeDBRA
and TimeSCCDB taken from real hardware with a suitable scaling factor.
