sensor: bmm150: Add I2C-base or SPI-base interface in build time

move DT_DRV_COMPAT to bmm150.h. so that can be decide which interface
to use.

define struct bmm150_bus_io interface for bmm150_i2c.c and bmm150_spi.c
in bmm150.h.

redefined bus operation interface in bmm150.c, this allow the driver
to decide which interface to use during construction.
