BLE 33 - .overlay updates, enable Wire1, pins match MBED, change AnalogRead to 12 bit

Extra pins:
```
 					<&gpio0 24 0>,	/* D22 LED R */
  					<&gpio0 16 0>,	/* D23 LED G */
  					<&gpio0 6 0>,	/* D24 LED B */
  					<&gpio1 9 0>,	/* D25 LED PWR */
  					<&gpio0 19 0>,	/* D26 INT APDS */
  					<&gpio0 17 0>,	/* D27 PDM PWR */
  					<&gpio0 26 0>,	/* D28 PDM CLK */
  					<&gpio0 25 0>,	/* D29 PDM DIN */
  					<&gpio0 14 0>,	/* D30 SDA2 */
  					<&gpio0 15 0>,	/* D31 SCL2 */
  					<&gpio1 0 0>,	/* D32 I2C_PULL */
  					<&gpio0 22 0>;	/* D33 VDD_ENV_ENABLE */
```
Note some of these pins are important to enable Wire1 to work.  Including enabling power to the sensors
as well as to enable the Pull up resistors on the Wire1 object.

Added Wire1 object to the list of wire bojects.
Set default clock-frequency on the two I2C objects, like the GIGA has defined.

Also changed the ADC conversion resolution for all of the channels from 10 bits to 12, as that is I believe
the maximum the device supports.  So when we pull in the PR for analogRead it should then map down to
the resolution the user chooses with analogReadResolution call.
