oled ext pwr: Apply ddudek OLED ext pwr patch

Browse source 
This commit properly reinitializes the OLED display after ext power is re-enabled.

It requires a patch pn zephyr itself.

Until the patch is implemented in zephyr, it can be applied in your zmk-config’s github build action.

More info here:
https://github.com/zmkfirmware/zmk/issues/674

Original code by ddudek can also be found in the above issue.
