The changes in mostly pin-muxing stuff, but also some minor fixes. In detail: - enable SPI pins - enable I2C pins - enable UART pins - enable LRADC pin - adjust USB DR mode - add default triggers for LEDs - get rid of regulators simple-bus container - adjust phy reset duration According to phy datasheet, 25ms are sufficient. This also reduces the time to boot the system.
