Changes since v1
================
- add patch to refactor struct ps2_gpio_data for clear separation between
RX and TX
- make all variables for IRQ timekeeping per-port and initialize them in
ps2_gpio_open()
This patch series implements the usage of ktime for IRQ timekeeping to
overcome:
(1) The resolution limitations of jiffies.
(2) Potential spurious IRQs generated by gpio controllers.
Besides that, based on the newly implemented timekeeping, it fixes a wrongly
suspected extra clock cycle for TX transfers and a race condition when
starting an immediate TX transfer based on data received from an RX transfer.

input: ps2-gpio: remove tx timeout from ps2_gpio_irq_tx()
input: ps2-gpio: don't send rx data before the stop bit
