mtd: spi-nor: move all micron-st specifics into micron-st.c
The flag status register is only available on micron flashes. Move all
the functions around that into the micron module.
This is almost a mechanical move except for the spi_nor_fsr_ready()
which now also checks the normal status register. Previously, this was
done in spi_nor_ready().
