[Breaking Change]fmuk66-v3: Only Support Rev BX11

   I2C bus chaged I2C0 is external, I2C1 internal
     Added BMM150 on I2C1 @ Addr 0x100
     Added BMP280 on I2C1 @ Addr 0x76

   UART0 (/dev/ttyS1) now used at Telem 2

   Chip select added for W25X40CLUXIG Calibration EE prom
     Driver is not added at this time
