Merge patch series "Fix driver for misc/atsha204a"

Michał Barnaś <[email protected]> says:

Fix the driver to behave like the chip datasheet requires.
Improve wake up function to send low signal on SDA line for at least
60us as chip requires to wake up. Fix sleep function to move the chip
into sleep mode, not into idle mode. Remove unnecessary for loop,
which would never run for more than one iteration.
