Max Regan 9d40f5026a cpu: change cpu cycle calculation

The Gameboy CPU runs at ~4MHz, but all the instructions take some
number of cycles divisible by 4.

This patch causes the cpu_cycle() to run a single 1MHz cycle, instead
of requiring 4 calls at 4MHz to perform the same emulation. Based on
the code in gbdb, the video controller now appears to run much slower,
and the timings needs to be verified.

This results in a large performance gain.
