H1x0/H300 remote LCD driver rework: * Completely fix remote LCD ticking for H300, by not deasserting CS after every single access. CS deactivation is now handled with a 100ms timeout by the tick task. If this really fixes remote ticking for all H300s with 'reduce ticking' disabled, we should remove that option for H300. * Reworked ticking reduction for H1x0. Bytes are now send in sequence, without stretching every single bit, but longer pauses between bytes instead. Both CLK and DATA are handled in a way to minimise their potential to cause ticking (CLK active as short as possible, DATA always high outside of byte transfers, DATA high->low as close as possible to CLK low->high). * Driver is ~10% faster with 'reduce ticking' disabled, and ~65% faster with it enabled. (not @ 11 MHz)
