As requested here [1], this fixes some of the style errors
introduced with the addition of l3g4200d support to the l3gd20
driver. Gyro orientation is set conditionally for the aerocore
board.

AeroCore uses ttyS0 not ttyS3 as the serial port connected to the GPS.
Now, a board can set GPS_DEFAULT_UART_PORT to override the default setting
in a board-specific fashion.

The L3G4200D chip is very similar to the L3GD20[H] parts and can use
the same driver with minor adjustments. There are four differences:
* WHO_AM_I register is 0xD3 (not 0xD4 or 0xD7):
- added an extra case to the driver probe
* Sampling rates are marginally different:
- setting sampling rate now depends on the detected chip
* I2C address range is different:
- no changes as the driver doesn't support i2c access
* the L3G4200D has a self-test function:
- no changes---chose not to implement feature in driver
