CC2520 can handle up to 8Mhz SPI SCLK frequency, thus let's use it. It
will help to avoid timing issuse while transmitting and receiving (i.e.:
getting registers or buffers from CC2520 through SPI will be fast and
won't impede RX/TX events too much).

The radio driver was using DW spi and gpio drivers hardcoded.
Now it will check if SPI_DW or SPI_QMSI is set.

These are the default ones for the internal CC2520 chip found on the
Quark SE SS devboard. GPIO 11 is used to emulate CS.

It's basically the same pinmuxer as in CTB with different external
sensors wired to it.
