I2C to the charger now has clean 100kHz timing. One read command now takes
400us, and one write command takes 300us to execute.

Option ROM contains some flags and configuration data for the MCU.
Things like oscillator configuration, HW reset pin enable, data EEPROM
enable, etc.

The longer duration is actually required, likely due to debouncing
applied on the SoC side. Even 50us was unreliable.
