[ECOS] arm SPI1 cdl bugfix, new variant support

[Szentirmai Gergely]

Hello

I have discovered an error in spi_at91.cdl

    cdl_option CYGHWR_DEVS_SPI_ARM_AT91_BUS1 {
    active_if     CYGINT_DEVS_SPI_ARM_AT_HAS_BUS1
        display       "Enable support for SPI bus 1"
        flavor        bool
        default_value 0
        description   "Enable this option to add support for the second
                   SPI peripheral. The most AT91 devices only have one bus"
    }


CYGINT_DEVS_SPI_ARM_AT_HAS_BUS1 is wrong, CYGINT_DEVS_SPI_ARM_HAS_BUS1 
is the right value.

And I added support for SAM7A3, and definitions for the MCI interface. 
What is the right way to post my changes?

Thanks!
Gergely Szentirmai
