Code Simplification: Reduce complications in check_I2C_EEPROM_ctr and t100ms_ctr usage

[nielsonm236]

These two counters evolved in usage and end up consuming more RAM than needed as each are uint32_t when they could be uint8_t. The way they are used required a lot of review when simple changes were being made to make sure there were not interactions in the timer / counters. Change: Renamed "check_I2C_EEPROM_ctr" to "I2C_EEPROM_ctr". Renamed "t100ms_ctr" to "restart_reboot_timer", Changed both to uint8_t and made their count processes independent of each other.
