There are some bug need to be fixed when we use the Up-to-date esp32 lib on Arduino

[graydonli]

Environment

• Core (if using chip or module): ESP-WROOM32
• IDF version b85e8e1
• Development Env: Arduino IDE
• Operating System: Windows
• Power Supply: USB

Problem Description

After i updated the hareware/espressif/esp32 directory using "git pull". Then the I2C module is halted whenever i used the I2C module on Arduino IDE.

The default I2C module has some bug. Maybe it is I2C0. The I2C module will be halted.

Please fix it quickly. Thank you！

The current Arduino release has a bug with ReSTART operations, I have a fix pending pr 1717 That fixes this problem.
