ARM: imx: change the way spi-imx devices are registered
Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX. The structs holding the actual data
are placed in .init.constdata and so don't do much harm. Compared to
the previous approach this reduces code size to call imx_add_spi_imx.
