H300: Optimised PCF50606 driver, significantly reduces CPU power drain from the button tick (with both main & remote buttons: 50%->13% at 11MHz, 12%->6% at 45MHz): * Delay is adapted to the current CPU clock, aiming at constant 400kHz i2c clock. * Reduced number of port accesses (accessing GPIO is very slow, especially with the atomic boolean instructions) by implementing an open-collector-like behaviour. * Time-critical functions implemented in assembler.
