Improved default pin mapping for I2C0 and UART1 to avoid issues with programming. SDA0 was on IO2 but IO2 needs to be pulled low on reset to enable serial programming, which conflicts with I2C pull-ups. RX1 was on IO12, idle UART level is high which conflicts with IO12 needing to be low on reset to select correct 3.3V flash voltage. New mappings: SDA0 on IO15 RX1 on IO13 TX1 on IO12
