boards/common/arduino-zero: Add Arudino SPI mapping

Browse Source 
The Arduino Zero based boards already provided the feature
`arduino_spi`, but were missing the corresponding mapping. This fixes
the issue by adding the SPI bus numbers for the ISP SPI bus and the
D11D12D13 SPI bus.

(And in order to actually add the D11D12D13 SPI bus, the `periph_conf.h`
was extended to provide an SPI configuration for it.)
