Enable multiread by default for LIS3MDL since using I2C interface
the subaddr Msb is used to automatically increase the slave address
during multiple data read/write. In the same way, using SPI interface,
bit 1 in register address is used to enable auto-increment of the slave
address in multiple read/write.
Fixes: 872e79add756 (iio:magn: Add STMicroelectronics magn driver)

Applied to the togreg branch of iio.git and pushed out as testing.
