fix speed halved in ESP32-WROOM-32E

Browse source 
ESP32 ECO3 added a configurable bit that will cause CAN bus speeds to be halved in new V3 core 32E module.
This bit is in `TWAI_INT_ENA_REG`, bit4 which was previously reserved.
Change respects reserved bit and should not cause issues for previous versions since this bit should not have been written to.
