[AVR32] Make STK1000 mux settings configurable

This adds some STK1002-specific config options covering the jumper settings,
so the kernel can automatically be configured to include the relevant devices.

One of them replaces the previous internal SW2_DEFAULT setting; SPI config
is affected by two of the jumpers; and a fourth one switches between LCD and
the second Ethernet connector.  (There's more that to be done.)

+          You will normally leave the jumpers on the CPU card at their
+          default settings.  If you need to use certain peripherals,
+          you will need to change some of those jumpers.

+        help
+          This also prevents using the external DAC as an audio interface,

+          If you change this you'll want an updated boot loader putting
+          the console on UART-C not UART-A.
