2.2.3 Add MAX3421E Support
What's Changed
- Support max3421e (usb host shield) for nrf52 and samd21/samd51 by @hathach in #334
- update all dual examples to support max3421e tested with samd21 and nrf… (samd 21 and 51 can only work reliably with SPI at 12Mhz)
- ESP32 Sync issue, more workaround for esp32 core - skip vendor_device.c entirely
