[PATCH] iio: magnetometer: hmc5843: Clean up redundant code.

[Song Qiang]

Regmap tables are both defined in hmc5843_spi.c and hmc5843_i2c.c, while
the only difference between these two set of tables is SPI need a read
mask, which is set only in 'regmap_config' structrue. This patch moves
the other structrues into hmc5843_core.c to reduce redundance.
