This reverts commit 519b4dba586198eed8f72ba07bc71808af2e0e32.
It is true that the actual implementation has never been there. But
contrary to what the reverted commit message says it does make sense
to add it.
Current implementation of the reset signal is hard-coded to active low
with the
The SSD130x OLED display reset signal is active low. Now the reset
sequence is implemented in such a way that DTS authors are forced to
define the reset-gpios property with GPIO_ACTIVE_HIGH to make the reset
work.
Add the reset-active-low property so the signal is inverted once again
