REVONANO - Fix Baro initialization bug

Browse Source 
The I2C SCLK pin (A8) was being changed by code used to support battery voltage sensing on the Revo. This code was run after PIOS_I2C_Init but before PIOS_MS5611_Init, causing a BUSY state on the I2C bus before the Barometer initialization code was run.
