Ramiro Polla 5803dca3b8 upd7810: use intermediate flip flops for extended timer/event counter 
The extended timer/event counter uses intermediate flip flops (LV0 and
LV1) before writing the output to CO0 and CO1.

The introduction of LV0/LV1 addresses three issues:
- Level inversion occurs after the flip flop is output, not before;
- The intermediate flip flop can be altered without affecting the
  output of CO0/CO1;
- upd7810_write_EOM() didn't work properly when the level inversion
  bit was set along other bits.

What is MAME?

MAME stands for Multiple Arcade Machine Emulator.

MAME's purpose is to preserve these decades of video-game history. As gaming technology continues to rush forward, MAME prevents these important "vintage" games from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the games are playable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully)?
